- We compare the new 2021 REL T/9X to the beloved REL T/9i. The REL T/9x is the largest subwoofer in REL's completely revised T series. Do the changes to the amp, cabinet, and driver deliver enough sonic improvements to warrant an upgrade?
Your host Duncan Taylor has used a pair of REL T/9i's for years to power the low end of his system, and he puts these new T/9x subs to the test.

Helpful review, thanks. - MonoDave from New Orleans
Excellent presentation Sir.
Hi Duncan, very useful thank you. I just took delivery of a T9x today - to replace a T5i (I was thinking of running both, but seriously there is no need I don’t think you’d even hear it, so will likely be going on eBay!!). Fantastic sounding sub I’m super-pleased with it straight off the bat it’s giving me extremely deep, clean bass with my AE309’s using the supplied Neutrik connection👌looking forward to further tweaking and fine-tuning over the next week or so.
I guess your idea of 'extremely deep' needs some rethinking. 27 hz (-6db) inroom. lolz.
@@Roof_Pizza That is deep.
I have 2 t5is mk1 and I love them!
Now I need a new REL> more reviews of new vs used, please!
Hey Duncan! Good stuff, hope to see more of these kind of videos!
Hi Duncan,
Very like your sharing. Anyway, I see you use Vicoustic Super Bass Extreme as bass traps, but they affect only 60-125Hz and most effective in 75-100hz. But Rel T9i or x can go down to 28hz. So is the Vicoustic appropriate for Sub Rel?
Hi Duncan
I have purchased one 9x and am waiting for a second to arrive. I have the Q Acoustics Concept 300s. Where did you set the crossover?
Thanks
Does this kind of downfiring passive radiator sub benefit from an isolation platform?
Hi Duncan, I have a single T/7i and have been planning get a second one. Do you thinks it’s worth adding a t/7x or should I stay within the same line and get another t/7i? Btw. big fan of the Podcast, some of it is over my head, but so much gold ❤️
@Duncan Taylor Awesome advice Duncan! Matches that of Rel support - use the X as the lead sub 👍
Have you heard the 510s; if so how do they compare? I have dual t9is and was thinking about upgrading, but thinking about stepping up to 510s
@denny b I agree
Nice ! I still have my old T1 that is over 15yrs old now and blew the amp by the lighting hit so 8 yrs ago REL service did sell me the new amp module for very reasonable price and since than it's been perfect .
I have a smaller 13x18 room and T1 feels it great and makes my Monitor stand speakers sound huge and powerful.
I always wondered what upgrade new version would bring , would it be better to get two T5s rather than one T9 ? My system is two channel stereo so could I connect these in mono configuration by using RELs speaker level connection method and how would I connect it than as each connector has 3 wires L,R , Ground ?
What is a 'very reasonable price'? I'm kinda thinking it isn't.
@@Roof_Pizza I think it was around 160usd for the amp module , it is super easy to replace at home in no more than 5 to 10 minutes ... This was in their Sumiko days , who knows how it would be now .
Blown up board would need 3 parts replaced , diode, resistor and cap as it looks like some sort of power surge destroyed them , and maybe I should have tried to repair it as it is easy single level SMD board if I remember correctly.
According to John Hunter, head designer for REL, the amps in the T9i and T9x are virtually identical, with just 'a few minor tweaks', but exactly the same power.
My understanding is the the limiters were tweaked to allow for greater peaks and push the amp a bit further. REL is generally very conservative with their specs. I compared the 5i to 5x and had a similar experience to TMR.
I’m doubtful about the remarks that the 9x will make bass sound evenly anywhere in the room. It’s not scientifically possible. A 50hz bass wave has a ~7 meter wave length, which is the size of a typical room. There will be peaks and valleys at that wave length… it’s just science.
What is that playing in the background?
The T/9x has an image more in line with what a subwoofer has to be. Its measurements are wider and lower compared to the T/9i.
I've got a stereo pair of the T/5x.. hooked up via high level/speakon to a BAT VK-75SE and there's no way of getting around the 60hz hum. REL has been absent for the most part in assistance, so not really a big fan of their customer support. I am a fan of TMR Audio as this is where I purchased the BAT amp. Customer support has been fantastic and I highly recommend doing business with this company.
Thanks Bill!
They state a work around in their manual if there is a hum. Also make sure your equipment is grounded and the electricity you provide is clean (plugged into a nice surge protector as opposed to super cheap extension cords or surge protectors). I spend $50 on a single surge protector at minimum and have never had an issue.
@@cyberathlete Thanks for the reply. I've tried all of the work arounds, even contacted the designer of the amp. Going low level RCA from the preamp to the sub eliminated the hum, but also eliminated 90% of the bass. I have everything running through a Furman Elite-15. I've reduced the volume on the subs to about 35%. Still have a slight hum. I guess I'll live with it.
Do the cables to your subwoofers ly parallel to some power cables? This could give the 60hz hum. And try to only ground one device, just your amplifier but not the subwoofers for example. It could be a potential difference between different grounded devices.
@@erikhoogantink8529 Thanks for the input, nope wires aren't in parallel and both subs are not grounded as that's the only way on my particular amp to hook them up. 3 wire speakon, Red/Yellow to terminal... black floating. I've learned to deal with it. Can't tell when playing music.. just at idle.
Hello everybody I own this subwoofer and I absolutely love it the best sounding subwoofer I have ever heard in my life I has subwoofers for as much as $4000 but this is my favourite one thing was wondering I noticed the light on the back never turns off which means I think the subwoofer never goes on sleep when it's not in use does it mean I have to turn it on and off every time or can it be left like that please help me with this thank you.
But can you stack them? 😉
What is the name of that white sound absorption material that you have in the background
That is the Vicoustic Multifuser DC2 - let us know if you are interested in treating your room Michael!
Ok, how much did they pay you?
Rel or Jl audio
JL audio of course. Rel is stuck in the 90s.
I really suggest you guys invest in a good camera or use someone who knows how to have it in focus. All of these closeups are pointless if it looks like I'm seeing it through the eyes of a 90-year old without his thick glasses.
y need to upgrade your speaker first.
100% agree with Duncan on this one. I guess it might depend on your room and speaker, but at least it transformed my B&W Nautilus 805’s from something I wanted to sell, to something I’ll likely keep forever (as I get other speakers too 🙈🍿)
Spent months!!!! Jesus H Christ - I set my 2 T9i's up in 10 minutes flat. In fact I swapped one for a 510. Basically - it's a bit bassier.
TX series design are copy of sumiko....
the T9x is £600, the new T9i is £4000 grab the T9x... the upgrade is marginal
Lots of talking, little info. Man, speed up the review! These rels look hideous, terrible design and 90s technology for a lot of money.
Hello, I am considering the T/9x. Could you tell me the dimensions of your room, please? I think mine may be similar. I am just a bit concerned that it may be too much for my room. Thank you for a great channel, I only discovered it this evening.
The dimensions of the room we tested and filmed in are approximately 11x22. The T/9x performed very well in there, and I would recommend starting with one and placing it into a structural corner at the front of the room, immediately behind the main front speakers. From there you can tweak and move it around to find the best response.
It also gives you opportunity to upgrade or perhaps go for a stereo pair in the future. Hope this helps!
Happy listening!
@@tmr_audio Thank you.
The new models always sound better ... 🤣 ... 🥱
