So true. Need to match the sub to the speaker/room size. I use an ambeo soundbar with 2 Rel HT1003s and it was just perfect. Nice clean basslines and no boom. I initially bought 2 HT1205s and it was a bit overpowering for the room, so the dealer recommended i try out the HT1003s and he was right.

Hey John, I have a 9x9 listening bedroom. My speakers are the Kef LS50 Wireless. I used your pairings tool and was suggested dual T5i’s or a single T7i. I have no room for two subs, so would one T7i be the correct choice, or would you recommend a single T5i?
If it is only possible to add a single subwoofer to your system at this time, then we recommend a T/7x, or an older T/7i, as being the best option for pairing with your KEF LS50s.
Im currently building a pair of Klipsch La Scalas with a built in bass box on the bottom. if the Rel subs sound good then i would definitely be interested In talking to someone for sure 👍

How about having different size subs in the same room 1205 and 1510. Should it be better to catch up small main speaker and maintain immediacy, and big bass
Thank you for reaching out. In a home theater system is is possible to use different sizes of subwoofers, and typically with the larger unit placed in the front of your room and the smaller unit placed in the rear of your room. For a 2-channel music system, if using two subwoofers in a stereo pair configuration we strongly recommend that both units be the same matching model, which will ensure that the system's sub-bass output is balanced and even from left to right. If you have any additional questions about implementing multiple subwoofers in your home audio system then feel free to write in to contactus@rel.net and we will be happy to assist.

John, I have a single T9/i that's sounding really great with a pair of full range Joseph Audio Pearl 3s in a 16'x23' room. I'm happy with the sound but wondering what would be the logical next step upgrade? Getting a pair or multiple T9/is or switch to a single S3 SHO or S/510?
Thank you for reaching out, and we are glad that you are enjoying the performance of the T/9i in your system. While the T/9i can pair well with the Joseph Audio Pearl 3 speakers, if you are interested in upgrading then moving up to an S/510 subwoofer would be an excellent choice for this system. The S/510 will be capable of delivering deeper and more dynamic sub-bass output, and blending more seamlessly with these main loudspeakers.

Though he adores REL products, Paul from PS Audio would have a field day tearing into John about categorizing a sub for music or home theater. A sub is a sub is a sub at the end of the day.
@@JPWinters Still not getting a CLEAR explanation of what designates a sub for music or theater. Im not talking different types of inputs it takes either.
@@AllboroLCD HT subs are generally ported, larger, go deeper and are a bit sloppy. Musical subs are more accurate, tighter/faster, usually smaller and don't go as deep and might be sealed. HT subs can start as low as 100 bucks US. I have no idea what the cheapest musical sub is but it's many multiples of that.
Thank you for reaching out. Since this system is being used in a fairly large room we typically would recommend a stereo pair of T/9x subwoofers as being a good match for your Focal Chora 826 speakers, though moving up in size to the S/510 will result in deeper low-frequency extension and more thorough pressurization of this room. If you have any additional questions about subwoofer pairing for your system then feel free to write in to contactus@rel.net and we will be happy to assist.

I still can't come to terms with ppl looking for the smallest footprint possible. It's a sub it's generally outta the way there the size of a small table. I feel like the the larger the box the more musical it is. Do someone to choose a smaller box over better sound quality is crazy to me especially when your talking about a sub 12" box or a 16-17" box the difference isn't that noticable in appearence but the sound is definably noticable. A subwoofer needs volume it's simply the physics of sound waves. And in my mind the physics of the sound waves I want to reproduce determines the size of the cabinet I chose. At this level of audio you have to be willing to give up a few extra inches of your listening area to achieve the best possible sound. Were spending thousands of dollars for the best sound possible. I'm not talking about putting 4 foot concert level dual 21" subwoofers next to your tv in your living room. But a 16" square box in your living room shouldn't be an issue. To a degree when it comes to sound bigger is better. It's not going to take over your living room
The notion that bigger is slower too...smh. Speed is a function of frequency. Acoustic suspension speakers are plenty snappy for me. Also, the thinking that you can put too much speaker in your room is also hilarious. Just turn it down if it's too loud. If you turn it up and end up with room issues, those issues are still there with a smaller speaker unless it doesn't dig as deap and at that point, you should fix the problem with placement and treatment not limit your sound. I have a large open plan space downstairs for our music and tv so I need to move a lot of air. Two 18" Ultimax in the right place gives me flat extension to 15hz.
If you are running a stereo pair of subwoofers in a 2-channel system, then we recommend that both units be the same matching model. This will help to ensure that the sub-bass output of your system is balanced and even from left to right. However, if your system is primarily used for multi-channel home theater and you are using the subwoofers in a REL-3D configuration (rel.net/blog/2017-06-15/setup-deep-dive/dive-real-deep-rel-3d/) then it is possible to use different sizes of subwoofers assigned to the different surround channels.

@Mark Man I like it so much that I don´t feel the need to upgrade. I was advised to buy T7 because for my room size there´s no need of a T9. Even if I needed more woofer area, I´d have chosen a pair of T7 instead of one T9. T7 blends perfectly with my magnepan. When I switch on the T7 seems like I upgraded the speakers, because I don´t "ear" the sub but the overall sound gets much better.
Rel T9i or T7i in combo with Jbl Hdi3800. Plan is 2 sub's. What do you think is the best combination with my speakers? My amplifier is a Yamaha A-s2100. Best regards from Norway 🙂🎸🎙🎵
The best choice of subwoofer for your system will depend on a few additional variables, though assuming that your system is placed in a medium-sized room then the T/9i will be the best option for pairing with your JBL-HDI-3800 speakers. If you have any additional questions regarding subwoofer pairing for this system, please write in to contactus@rel.net and we will be happy to help.
John, I’m running a pair of Tekton Pendragons and am at a loss. I’ve tried numerous subs, but none really seem to synch up in a pleasing and smooth, seamless manner. They go low, supposedly go from 20hHz - 30kHz, which is obviously not linear. Any ideas? Thanks in advance.

I currently have a T/7x on home trial, but could use some more deep bass and bass pressure. My worry is whether the T/9x is as fast as the T/7x, which I heard was around 8 mS (correct?), since my main speakers are quite fast responding. Could someone from REL maybe clarify this? Thanks.
Thank you for reaching out, and for supporting REL Acoustics. The T/9x is just as quick and responsive in it's output as the T/7x, and if you are looking for deeper low-frequency extension in your system compared to the T/7x when moving up in size to the T/9x would be a valid option. If you were looking for faster and more responsive output from the subwoofer in addition to deeper extension, then we would recommend moving up in size to one of our Serie S models like the S/510.
FYI, @RELAcoustics, I ended up choosing to go directly to a S/812 for my main system, since I found an 'open-box' item with a good discount. It's a really great match for my speakers - they are more than ever reproducing real music and no longer so much 'only hifi'. I am a very happy customer 😊
My Uncle Ned said the bigger the subwoofer the more bass you will receive.... My Uncle Ned is the smartest guy in the room, and he's in a lot of rooms.
I am building a system using a 3" speaker linearray for home theater it will go down to roughly 100hz i was thinking of crossing it over to two 10" woofers around 150-200hz and then have those trade off to a 18" subwoofer around 60-80 hz to handle the real low end , is this a good idea or no? everything will be run off a dsp
@denny b so it's for my computer and I'm missing the punch and impact when playing games and movies , it's a small room , the line array is 8 per side I wanted to get as much cone area for impact with out going wide cause I don't have room and I was going to do two flat 10s under my desk and do the one 18 off to the side , I don't think I would be able to fit two 18 , I never had an 18 before and it's a local company that makes subwoofers I want to support and they start at 18" and make up to 32", also I wanted to go the theater idea of having two duties for subwoofers and keeping everything playing In the optimum playing range so nothing is ever stressed or near its limits
@denny b thank you , right now I have a older kef 12" subwoofer , but not getting the lows I want , it was made in 1993 so I understand 12s have evolved , what 8 would you suggest and would suggest multiple of them and I know the company does custom too so maybe they can make me one or a few, also I haven't built the line array yet , do u think it's a good idea because of the space and what I want ?
@@zorhis1996 if you don’t mind me stepping in here. I have dual 12 in subs. One firing downward in a smaller family room. I was disappointed in the bass performance. The actual problem was that the room was too small. I put it in a larger living room setting and wow. Crazy solid and deep bass. The other person is correct when he says 18 inch subs are overkill in the room you have. A Kef subwoofer is more known for sweet natural and musical sound. I don’t think it’s made for gaming and home theatre. Continue to research and ask questions. The set up you suggested sounds pretty good too but only in a large room with high ceiling. It seems most who are into home theatre go with SVS these days. People that listen to 2 channel music go with Rel more. But with the size of your room I can see Rel doing very well too for gaming. I never even heard either subwoofer but they both seem very popular here on YT.
@@f430ferrari5 well this one I'm looking to build , I already have a very nice musical system in my main listening room. I want this to be loud and alot of impact , so now I'm think maybe 4 8" or something similar , I might be able to fit 2 8" enclosure on each end of my room diagonally , would that be better then just on one side ?
@@zorhis1996 the 4 x 8 in concept sounds good but before moving forward..are you able to try any equipment from your main system into the smaller room? My understanding is having multiple subs in a room like place diagonally is more to help balance the bass where it sounds good in any listening position. So it’s like you want a whole audience to enjoy. It seems to me the game room is just for yourself? So it’s just a matter of placing a sub in the right position? Currently your Kef sub is in a corner of the room? Maybe due to room acoustics there is flat spot from where you are sitting? Have you tried moving the Kef sub around the room? It’s hard to know what kind of bass are you looking for too. Maybe for reference. I’m sure you’ve seen YT vids where in car audio a person’s hair is flying around all over the place. Are you looking for this type of pressure or somewhere close?
Thank you for reaching out, and for your interest in REL subwoofers. The ideal choice will depend on the size of your room that the system is placed in; for a smaller room the T/5x would be a good choice, though if your room is medium-to-large it would be worth moving up in size to the T/7x.
John, I am considdering two t5x's vs one t7x to pair with my Harbeth c7x speakers. The system is used for both music and TV, but music had priority in gear choises. My living room is 6 by 5 by 3.2. That is in meters, by the way - a volume of about 3400 cubic feet. It's a question of integration vs extension. I lean towards the two smaller units - am I right?
Based on the size of your listening room I would actually recommend the single T/7x as being the preferred option for pairing with your Harbeth C7ES speakers, with the eventual goal of adding a second later on to make a stereo pair. Compared to the T/5x, the T/7x has a quicker and more dynamic output while also being able to reach deeper in it's low-frequency extension, which enables it to blend far more seamlessly with these speakers.

That’s surprising. Can you supply some information about the Gato amp you’re using? We aren’t aware of many amplifiers that can’t have a subwoofer connected high level.
@@matthewtodd3879 Thank you for providing this information. You will be able to connect the Tzero to your Gato integrated amplifier using the High Level input, though since it is a Class D amplifier it will be important to not connect the black wire of the High Level cable to either of the negative output terminals on the amplifier.

A subwoofer speed is largely a function of lower group delay. Does Rel publish any measurements of output and group delay to justify their claims of superior speed? A 7/9 inch sub trying to produce 30hz at avg listening volume would need to work much harder - go in and out pistonically at a much greater distance than a much larger woofer. This is because the woofer needs to move a substantial amount of air to produce lower frequencies.
Thank you for reaching out. Our Reference Series subwoofers have a filter circuit group delay of 4 ms, and all of our other current subwoofer models have a filter circuit group delay of 8 ms. However, other components also impact the speed of the subwoofer, including the unit's driver and amplifier design. I these cases, we use extremely lightweight-but-rigid drivers and high-current amplifiers with exceptional damping factor, all of which allow for exceptional dynamics and a seamless blend between the subwoofer and your main loudspeakers.
Room size/dimensions, the model of main loudspeakers, and the model of amplifier which you are using to power those speakers all have an impact on which subwoofer is the right choice for a system. If you have any questions about which of our subwoofers is the right choice for your system, feel free to write in to contactus@rel.net and we will be happy to help.

@Khaled Sherbini What did you end up with?
I have a pair of Magnepan .7 speakers. Are REL subwoofers fast enough to transparently blend? What model? My room is 4.2 m by 5.7 m. I will use a 2-way Marchand XM9 active crossover to feed the lows to one or two subs (what is the best option?) and the mids/highs to power amp (Hegel H190) and then to the Maggies. Thanks!
Thank you for reaching out, and for your interest in REL subwoofers. At REL, we put a high priority in making sure that our subwoofer models are as fast and responsive in their output as possible, which enables them to blend seamlessly with traditional cone drivers and electrostatic panels like your Magnepans.

How about having different size subs in the same room 1205 and 1510. Should it be better to catch up small main speaker and maintain immediacy, and big bass
Thank you for reaching out. In a home theater system is is possible to use different sizes of subwoofers, and typically with the larger unit placed in the front of your room and the smaller unit placed in the rear of your room. For a 2-channel music system, if using two subwoofers in a stereo pair configuration we strongly recommend that both units be the same matching model, which will ensure that the system's sub-bass output is balanced and even from left to right.
If you have any additional questions about implementing multiple subwoofers in your home audio system then feel free to write in to contactus@rel.net and we will be happy to assist.
@@RELAcoustics thank you very much for your information I am using a s812 for my music listening room, then just planning on buying one more for another channel.
The biggest REL you can afford
John, I have a single T9/i that's sounding really great with a pair of full range Joseph Audio Pearl 3s in a 16'x23' room. I'm happy with the sound but wondering what would be the logical next step upgrade? Getting a pair or multiple T9/is or switch to a single S3 SHO or S/510?
Thank you for reaching out, and we are glad that you are enjoying the performance of the T/9i in your system. While the T/9i can pair well with the Joseph Audio Pearl 3 speakers, if you are interested in upgrading then moving up to an S/510 subwoofer would be an excellent choice for this system. The S/510 will be capable of delivering deeper and more dynamic sub-bass output, and blending more seamlessly with these main loudspeakers.
For more information, please write in to contactus@rel.net and we will be happy to assist.
@@RELAcoustics Thanks for the reply. Just to be clear, would you recommend a single s/510 over multiple T9i?
@@divertiti Based on the size of your room and for pairing with these speakers, a single S/510 will offer improved performance over a pair of T/9x.
@@divertiti they may be correct. Keep in mind they do make more money this way.
Get the 12" subwoofer, if you are thinking about a 10" subwoofer. Only get the 15" if your room is large.
My room size is 15’ x 20’ and I’m running a pair of Klipsch Forte iii’s (placed per Klipsch recommendation in front corners) for stereo listening only. Do not want overpowering base, just an overall enhanced depth.Not sure what to go with, i.e., T/9x or …? There isn’t much room along front wall width 15’ so I’m not inclined to look for two subs. Appreciate your thoughts and recommendation.
Based on the dimensions of your room, we recommend the T/9x as being the best option for pairing with your Klipsch Forte III speakers. For more information about subwoofer pairing for this system, please write in to contactus@rel.net and we will be happy to assist.
I only listen to stereo. I have a pair of Altec Lansing Model 19 speakers driven by a 300B PSE power amplifier. I also have an OPPO 105 AU which is used predominantly for CDs but on occasion the odd DVD or for the TV. I use the stereo RCA outputs from the OPPO but believe it might be possible to use the low frequency output from the OPPO to drive a powered Subwoofer. The room is approximately 45m2. Which sub (if any) would you recommend and why?

Though he adores REL products, Paul from PS Audio would have a field day tearing into John about categorizing a sub for music or home theater. A sub is a sub is a sub at the end of the day.
I disagree.
@@Roof_Pizza Then find me a top model "music" sub and a top model "theater" sub then break down the difference if you may.
Totally disagree & I've owned plenty of different subs in 2-channel. And Paul McGowan & PS Audio are not without their faults.
@@JPWinters Still not getting a CLEAR explanation of what designates a sub for music or theater. Im not talking different types of inputs it takes either.
@@AllboroLCD HT subs are generally ported, larger, go deeper and are a bit sloppy. Musical subs are more accurate, tighter/faster, usually smaller and don't go as deep and might be sealed. HT subs can start as low as 100 bucks US. I have no idea what the cheapest musical sub is but it's many multiples of that.
I have the focal chora 826… I’m in a 30’ wide by 24’ deep room with partially vaulted ceiling. What size sub? What Rel sub? Thanks
Thank you for reaching out. Since this system is being used in a fairly large room we typically would recommend a stereo pair of T/9x subwoofers as being a good match for your Focal Chora 826 speakers, though moving up in size to the S/510 will result in deeper low-frequency extension and more thorough pressurization of this room.

Hey John and Team,
We are building a home Theater and selected 2 KEF Q950 Floorstanding Speakers and 1 KEF Q Series Q650c Center Channel Speaker along with a Marantz SR6015 receiver and 2 pairs of KEF Q350 Bookshelf Speakers for side and back walls and 1 pair of KEF Ci200QR Round ceiling speakers for 9 channels and now we need to decide on the subwoofer setup for a 500 sq ft rectangular room that’s 20 ft by 25 ft. How many inch subwoofers and how many sub woofers do you recommend for this setup ?
Was considering rels as I heard amazing reviews by my friends but also hearing svs and others too so we are confused.
Thanks!
Thank you for reaching out, and for your interest in REL Acoustics subwoofers!

I still can't come to terms with ppl looking for the smallest footprint possible. It's a sub it's generally outta the way there the size of a small table. I feel like the the larger the box the more musical it is. Do someone to choose a smaller box over better sound quality is crazy to me especially when your talking about a sub 12" box or a 16-17" box the difference isn't that noticable in appearence but the sound is definably noticable. A subwoofer needs volume it's simply the physics of sound waves. And in my mind the physics of the sound waves I want to reproduce determines the size of the cabinet I chose. At this level of audio you have to be willing to give up a few extra inches of your listening area to achieve the best possible sound. Were spending thousands of dollars for the best sound possible. I'm not talking about putting 4 foot concert level dual 21" subwoofers next to your tv in your living room. But a 16" square box in your living room shouldn't be an issue. To a degree when it comes to sound bigger is better. It's not going to take over your living room
The notion that bigger is slower too...smh. Speed is a function of frequency. Acoustic suspension speakers are plenty snappy for me. Also, the thinking that you can put too much speaker in your room is also hilarious. Just turn it down if it's too loud. If you turn it up and end up with room issues, those issues are still there with a smaller speaker unless it doesn't dig as deap and at that point, you should fix the problem with placement and treatment not limit your sound. I have a large open plan space downstairs for our music and tv so I need to move a lot of air. Two 18" Ultimax in the right place gives me flat extension to 15hz.
Is it possible to mix different subwoofers with different size in a room, provided it is big enough ?
If you are running a stereo pair of subwoofers in a 2-channel system, then we recommend that both units be the same matching model. This will help to ensure that the sub-bass output of your system is balanced and even from left to right.
However, if your system is primarily used for multi-channel home theater and you are using the subwoofers in a REL-3D configuration (rel.net/blog/2017-06-15/setup-deep-dive/dive-real-deep-rel-3d/) then it is possible to use different sizes of subwoofers assigned to the different surround channels.
Hi John & Team,
I only listen to stereo. I have a pair of Q Acoustics Concept 40 speakers driven by Rega Brio amp. The room is approximately 32m2. Which sub (if any) would you recommend? Thank you !
Thank you for reaching out. Based on the size of your room the T/7x will be the best option for pairing with your Q Acoustics Concept 40 speakers.

Hi, I got the Canton Vento 826.2 bookshelf speakers on speaker stands driven by a Denon DRA-800-H amplifier.
I'm using my stereo system for critical music listening only (no home theater use).
The set up is in my 20 m² living room (4.7m X 5.4m) opposite the sofa (ca 2.6m distance between speakers and listening position.
Im thinking about getting a REL sub for my stereo system. Do you recommend the new model T/7x or T/5x ?
thx for the advice. :)
Thank you for reaching out. Based on this description of your room and equipment, we recommend the T/5x as being the best option for pairing with your Canton Vento 826.2 speakers.

@@RELAcoustics great thx a lot for your help! when will the x 5 be available at dealers in Austria/Germany? best Mario
Which ones will be best for Magnepan .7 in a medium size room?
I use rel T7 with magnepan 1.7.
For use in a medium sized room, the T/7i is an excellent choice for pairing with your Magnepan .7 speakers.
@Mark Man I like it so much that I don´t feel the need to upgrade. I was advised to buy T7 because for my room size there´s no need of a T9. Even if I needed more woofer area, I´d have chosen a pair of T7 instead of one T9. T7 blends perfectly with my magnepan. When I switch on the T7 seems like I upgraded the speakers, because I don´t "ear" the sub but the overall sound gets much better.
I have a pair of Sonus Faber Concerto standmounts in a 40 m2 (400 square feet) size room. Should I opt for an S/510 or T/9x?
In our experience the T/9x will be the best option for pairing with your Sonus Faber Concerto speakers in this size of room.
@@RELAcoustics Thank you for the feedback!
Rel T9i or T7i in combo with Jbl Hdi3800.
Plan is 2 sub's.
What do you think is the best combination with my speakers?
My amplifier is a Yamaha A-s2100.
Best regards from Norway 🙂🎸🎙🎵
The best choice of subwoofer for your system will depend on a few additional variables, though assuming that your system is placed in a medium-sized room then the T/9i will be the best option for pairing with your JBL-HDI-3800 speakers. If you have any additional questions regarding subwoofer pairing for this system, please write in to contactus@rel.net and we will be happy to help.
John, I’m running a pair of Tekton Pendragons and am at a loss. I’ve tried numerous subs, but none really seem to synch up in a pleasing and smooth, seamless manner. They go low, supposedly go from 20hHz - 30kHz, which is obviously not linear. Any ideas? Thanks in advance.

@@RELAcoustics I didn’t realize you’d gotten back to me, so firstly, thank you for that. I will be in touch in the near future. Thanks again!
I currently have a T/7x on home trial, but could use some more deep bass and bass pressure. My worry is whether the T/9x is as fast as the T/7x, which I heard was around 8 mS (correct?), since my main speakers are quite fast responding.
Could someone from REL maybe clarify this? Thanks.
Thank you for reaching out, and for supporting REL Acoustics. The T/9x is just as quick and responsive in it's output as the T/7x, and if you are looking for deeper low-frequency extension in your system compared to the T/7x when moving up in size to the T/9x would be a valid option. If you were looking for faster and more responsive output from the subwoofer in addition to deeper extension, then we would recommend moving up in size to one of our Serie S models like the S/510.
FYI, @RELAcoustics, I ended up choosing to go directly to a S/812 for my main system, since I found an 'open-box' item with a good discount. It's a really great match for my speakers - they are more than ever reproducing real music and no longer so much 'only hifi'. I am a very happy customer 😊
@@mr.hansen5195 Congratulations on your new S/812, and we are glad to hear that you are enjoying it's performance in your system!
My Uncle Ned said the bigger the subwoofer the more bass you will receive.... My Uncle Ned is the smartest guy in the room, and he's in a lot of rooms.
I am building a system using a 3" speaker linearray for home theater it will go down to roughly 100hz i was thinking of crossing it over to two 10" woofers around 150-200hz and then have those trade off to a 18" subwoofer around 60-80 hz to handle the real low end , is this a good idea or no? everything will be run off a dsp
@denny b so it's for my computer and I'm missing the punch and impact when playing games and movies , it's a small room , the line array is 8 per side I wanted to get as much cone area for impact with out going wide cause I don't have room and I was going to do two flat 10s under my desk and do the one 18 off to the side , I don't think I would be able to fit two 18 , I never had an 18 before and it's a local company that makes subwoofers I want to support and they start at 18" and make up to 32", also I wanted to go the theater idea of having two duties for subwoofers and keeping everything playing In the optimum playing range so nothing is ever stressed or near its limits
@denny b thank you , right now I have a older kef 12" subwoofer , but not getting the lows I want , it was made in 1993 so I understand 12s have evolved , what 8 would you suggest and would suggest multiple of them and I know the company does custom too so maybe they can make me one or a few, also I haven't built the line array yet , do u think it's a good idea because of the space and what I want ?
@@zorhis1996 if you don’t mind me stepping in here. I have dual 12 in subs. One firing downward in a smaller family room. I was disappointed in the bass performance.
The actual problem was that the room was too small. I put it in a larger living room setting and wow. Crazy solid and deep bass.
The other person is correct when he says 18 inch subs are overkill in the room you have.
A Kef subwoofer is more known for sweet natural and musical sound. I don’t think it’s made for gaming and home theatre.
Continue to research and ask questions. The set up you suggested sounds pretty good too but only in a large room with high ceiling.
It seems most who are into home theatre go with SVS these days. People that listen to 2 channel music go with Rel more.
But with the size of your room I can see Rel doing very well too for gaming. I never even heard either subwoofer but they both seem very popular here on YT.
@@f430ferrari5 well this one I'm looking to build , I already have a very nice musical system in my main listening room. I want this to be loud and alot of impact , so now I'm think maybe 4 8" or something similar , I might be able to fit 2 8" enclosure on each end of my room diagonally , would that be better then just on one side ?
@@zorhis1996 the 4 x 8 in concept sounds good but before moving forward..are you able to try any equipment from your main system into the smaller room?
My understanding is having multiple subs in a room like place diagonally is more to help balance the bass where it sounds good in any listening position. So it’s like you want a whole audience to enjoy.
It seems to me the game room is just for yourself? So it’s just a matter of placing a sub in the right position?
Currently your Kef sub is in a corner of the room? Maybe due to room acoustics there is flat spot from where you are sitting?
Have you tried moving the Kef sub around the room?
It’s hard to know what kind of bass are you looking for too. Maybe for reference. I’m sure you’ve seen YT vids where in car audio a person’s hair is flying around all over the place. Are you looking for this type of pressure or somewhere close?
What sub you recommend with Proac K1 ?
Thank you for reaching out, and for your interest in REL subwoofers. The ideal choice will depend on the size of your room that the system is placed in; for a smaller room the T/5x would be a good choice, though if your room is medium-to-large it would be worth moving up in size to the T/7x.
John, I am considdering two t5x's vs one t7x to pair with my Harbeth c7x speakers. The system is used for both music and TV, but music had priority in gear choises. My living room is 6 by 5 by 3.2. That is in meters, by the way - a volume of about 3400 cubic feet. It's a question of integration vs extension. I lean towards the two smaller units - am I right?
Based on the size of your listening room I would actually recommend the single T/7x as being the preferred option for pairing with your Harbeth C7ES speakers, with the eventual goal of adding a second later on to make a stereo pair. Compared to the T/5x, the T/7x has a quicker and more dynamic output while also being able to reach deeper in it's low-frequency extension, which enables it to blend far more seamlessly with these speakers.

@@RELAcoustics Really? Ok, thanks! I will certainly be in touch if I see any trouble setting up. Thanks again..
I nearly bought Tzero but Gato who make my amp said i cant connect the sub with the suplied cable to the amp ,it put me off
That’s surprising. Can you supply some information about the Gato amp you’re using? We aren’t aware of many amplifiers that can’t have a subwoofer connected high level.
@@RELAcoustics hi thanks for your interest,its the Gato dia 250 npm aniversary integrated amp,,regards matt
Think it was because its class D
@@matthewtodd3879 Thank you for providing this information. You will be able to connect the Tzero to your Gato integrated amplifier using the High Level input, though since it is a Class D amplifier it will be important to not connect the black wire of the High Level cable to either of the negative output terminals on the amplifier. For more information and complete connection instructions, here is a link to our video on connecting High Level to Class D amplifiers: th-cam.com/video/3F5WTOu60hE/w-d-xo.html
@@RELAcoustics thank you very much,you are a fantastic company
I have paired rel t5i with emotiva tzero in my 14*12*10 feet room i love its performances.
NOW i am moving to another room thats 20*18*11 feet room is adding another t5i sufficient.
will two t5is give good bass in 20*18 ?
A pair of T/5i subwoofers can work well in a 20'x18' room, and will help to more adequately fill and pressurize this space.
@@RELAcoustics Thanks a lot for clarifying my doubt I will get one ..
What woofer would you recommend with the AER speaker?
At your earliest convenience, feel free to write in to contactus@rel.net and we will be happy to provide a custom subwoofer pairing recommendation specific to your system.
A subwoofer speed is largely a function of lower group delay. Does Rel publish any measurements of output and group delay to justify their claims of superior speed? A 7/9 inch sub trying to produce 30hz at avg listening volume would need to work much harder - go in and out pistonically at a much greater distance than a much larger woofer. This is because the woofer needs to move a substantial amount of air to produce lower frequencies.
Thank you for reaching out. Our Reference Series subwoofers have a filter circuit group delay of 4 ms, and all of our other current subwoofer models have a filter circuit group delay of 8 ms. However, other components also impact the speed of the subwoofer, including the unit's driver and amplifier design. I these cases, we use extremely lightweight-but-rigid drivers and high-current amplifiers with exceptional damping factor, all of which allow for exceptional dynamics and a seamless blend between the subwoofer and your main loudspeakers.
I'm sure room size is also a factor.
Room size/dimensions, the model of main loudspeakers, and the model of amplifier which you are using to power those speakers all have an impact on which subwoofer is the right choice for a system. If you have any questions about which of our subwoofers is the right choice for your system, feel free to write in to contactus@rel.net and we will be happy to help.
