- เผยแพร่เมื่อ 11 ธ.ค. 2019
- This small transmission line subwoofer really hits beyond its weight! The driver is from Tang Band (W4-2089 4.5" RBM Mini Flat Panel Subwoofer 4 Ohm). It is a really easy build, and would be an ideal companion in the trunk of a car or for a small desktop speaker setup.
Suggest amplifier power: 80W (RMS)
High-pass filter: 35Hz, Low-pass filter: 160Hz

Once again a fine build. I always look forward to watching your videos, partly also because of your choice of music in your videos, which is always excellent! I always have a good time when watching your videos! Thanks!
Thanks so much!
boss, why is the port added a silencer? what is the function?
Very well done, I listened with a nice pair of headphones and it has an impressive range. Thank you for sharing!
Many thanks!
Love this channel. So interesting watching a craftsman about his work. Subscribed. 👍
Thanks
@@SoundBlab what will happen if u put a bass radiator in front of the bass port
Small but sounds like a big sub. I like the sound quality of the bass.
Cool build. The actual science behind the build would make for alot more views. Id like to learn the port science.
Thanks
My DIY TL sub measures 1½ feet wide, 4⅔ feet high and 2⅓ feet depth. Produces sound that propagate on floor. Real nice subsonic sound.
Great video, i really enjoyed this!
Dankie 😊
Это изумительно пропорциональная и эстетичная вещь! Это говорит о том, что правильная техника всегда выглядит прекрасно, так как всё в ней направлено на функциональность, а не на броский дизайн, рассчитанный на широкого потребителя. Браво 100000000! Спасибо и всего наилучшего! Просто супер!
Thanks!
Stunning build boet!
Thanks!
👍🏻 Good work as always ! From Germany 🇩🇪
Thank you!
@@SoundBlab you didn't take my design for a subwoofer 😢
Nice design!
Thanks!
@@SoundBlab I was going to say: 'Put it in your car and see how it performs.' Its a little monster of a thing.
would have been great to maybe use a di-pole driver to see how much audio spectrum you could cover with just that enclosure. Great build BTW, always enjoy watching your creative new projects.
I should know better to watch how I say things. I understand what you're saying, and I understand the complexity of tuning transmission lines. Thank you for highlighting my failure in the english language.
Impressive. I would add a bit more stuffing to tighten it up a bit. I'm listening to it through my two 12" subs and I can't believe how low it goes.
Impressive results
Thanks
Good work Man. From BRAZIL
Tx
But dude this is perfect!!
Tx
Simply superb
Thank you!
I love these videos!👍🏻
Thanks!
I would cover with grill of some sort. and maybe carpet the housing.
Beautiful build.

I love the tang band woofers. No other company makes them like they do.
I'm gonna use the 5 1/4 inch subwoofer and a slightly larger box.
Cool
i really do appreciate those tang band subs, i used to have a z2300 but the amp died and then a few days ago i decided to build a new enclosure for it and it bangs.
The sub that was used in the Z2300 is the Tang Band W8-670Q which is now fitted into a ~100Liter enclosure tuned to 30Hz which gives me a F3 of around 27Hz and a relatively flat respone
Brilliant, love it!
Thanks
So interesting watching this video nice finish job
Thank you very much!
Nice work sir
Tx
Solid bass 💪
👊
I do wish I could get this Subwoofer in my part of the world! Shipping to NZ is a killer!
would really appreciate a video like this for a 10" or 12" subwoofer
Might be a very large enclosure, but I am also interested to do something like that. Maybe future video...
@@SoundBlab I used a ceramic sewer pipe for a 25cm diameter woofer, 70ish cm high, 40cm total diameter. They need not be too large if you can make the material dead. Sewer pipes can be had here and there for bargains, unused, maybe where you are too?
You could also optimise by floor size, I have another sewer pipe, but plastic (other materials too heavy), it is cheap, only 25cm total diameter, and comes in standard length of 5,5m. So, I cut it down to 2,40m exactly to me ceiling, now I need a way to put it upright and be stable enough. IIRC 90cm or so of 10cm reflex pipe will put me at up to 18Hz flat.
Big pipes are easy and good. For subs anyway.
@@jamegumb7298 can you make that shaped as many S, so its more compact under a couch?
T-Line boxes, by nature are not compact.
@@OlavAlexanderMjelde Using a ceramic sewer pipe? Unlikely. Plastic sewerpipe? Probably if you have the connector pieces but no idea how that will affect the sound, sharp corners, and 25cm across still means a rather high couch. I optimized for least amount of floorspace, to just take in vertical space instead, not tiny size in general because it really is not.
the stuffing is at the beggining of the line
lol
Bass is awesome 👍👍👍👍👍👍
Thanks
Great diy product build sir 😀👍🇧🇩
Thanks!
Good work! Frequency response from 55Hz-60Hz - I think so
Great color
Thanks
can you show as how its sound when is on the car ? :) love this small projects :)
good. perfect project
Thanks!
6:58 im in love.
Cool 😎 subwoofer and sound
Thanks! 😃
You'are welcome
Very very nice
Thanks a lot
Wow exelents sounds of woofer
Thanks
nice sound quality
Thanks
Keep it that way , Soundblab.
Greetings from Costa Rica and feliz navidad.
Thanks!
It's really flat in the responce, smooth and tight.... is there a video on small battery powered amps as I'm thinking of a portable system with a extra amp to power this when there space and time for the exta subwoofer... Intresting for live song making in the woods or on a mountain
Nice video if u can plan a slim hideaway sub so that the home minister doesn’t complain. Would be great. Also slim line array using Tang band sound modules
Nice job
tx
Nice build! I found a cordless brad gun at the pawn shop and I can't understand ever attempting to build a sub or any cabinet without one!
Yes, definitely one of my most used tools!
Good job 🔊 🎶👌

That thing hits hard😯
Hi a suggestion, cover the reflex bass hole with a mesh.
Made my first with some old tear down parts of old stuff, not as small, due to needed to be at least 12”x14”x and went with x 10 sidewall which placed ext. wall and act as side ports for surround acoustic with additional top ported tube. I have very minor knowledge on boxes or properly distributing sound. The 4” micro sub is in its own separate box within the box as sorta of a double boxed concept acting as a double semi compressed bass -air-per-cubic ft. Which i was iffy about. And only using 2 smaller 3inch full range audio speakers in front of box and i only designed 2 split sound walls to control the acoustic to ported sidewalls , which front to rear go 7 inches to back- once again i have no clue what i am doing , to know whats best. Lol just and idea of how i thought i wanted it to work with lil to no knowledge . Let me tell you something though. The quality of 300deg. Sound shocked more than just i ! They bass shakes whatever you did not know was loose in the house or area. The neighbor from 3rd floor , i do not even know , as i walked out to put into car before work to get some paint on it , asked if that was playing on and off last couple days? I replied yes as i was checking to see sub hertz range for 6-7 min. Each time. He replied -wth ! That is one bad*** loud box , it can shake somethings in here and i thought it was someones subs in a car. Lol -note these are very newly built solid and very quite apartments and that was the 3rd floor. My wife won’t even let me play it in the house . But i did noticed the 2” x1” side ports built in sidewalls were not enough and i thought would be too much or plenty for the small pre-boxes sub at base of box , but they were actually not enough i found out later on accident . So i ended up putting a flush port tube at the rear top of box and that increased bass and the bass quality of surround as the speakers were already. I think the reason for this was , that on the sidewalls i decided to close the side ported areas off box with audio mesh for a nice, clean look and it cut down on the air to be able to exit box as much as did before and compresses against self. So the ported tub on top helped not only get that back , but made it even better in all aspects. Never expected that lil sub to need so much air . Given its pre-box size is 12x14x3.75
good stuff!!
Thanks
Excellent 👌
Thanks a lot 😊
I would incorporate that into a high efficiency Bluetooth boom box build.
Phase in t-line speakers is a trip. Should I first just make the enclosure and then add volume inside the case to unify the phase?
Can you add weight to the passive radiator, because in 5 liter tuned to 30 hz you get flat responce from 30 to 80 hz.
This sounds amazing
tx
Please, give me dimensions of these project. Thank You!
Beautiful and detailed video. Thanks
Thanks
@@SoundBlabhow did you modeled the box. i can model in hornresp but i cannot be sure if im getting the box modeling / calculation part right. i easily desing bandpass abc vented or sealed enclosures but horn based ones such as t line seems so hard
@soundBlab nice clean looking build. Can you share your hornresp model?
great! ❤
I can see that having a table saw making accurate cutting really easy . It's not so easy free hand with a circular saw
It does, but only if set up accurately. You can use a guide rail with the circular saw and still get very accurate cuts.
@@SoundBlab you can also take a cut sheet to your timber merchant and they will pre-cut stock to size for you to an accuracy of plus minus a couple of mm, which can then be flush trimmed to final size with a router and a metal guide rail if you need absolutely hair-splitting accuracy.
You can get some linear guides for a circular saw. Very effective! And cheap!
@@weareallbeingwatched4602 That's what I do. I'm not going to make things way harder for myself just to save pocket change.
Great Work Bro.Keep it up.Please tell me box and port dimensions.
Nice build, you should make one that fits in the spare tire compartment.
shakalg1 not that hard...
Thanks!
Nice sound impressive

@@SoundBlab no problems ❤️
Very cool

Retro Style Boombox + Transmission Line Subwoofer. Sound demo on both, maybe?
The sound demos for these are separate videos. Go check on my channel for the vids.
How it's sound?,looks similar with Bose accoustimas design
nice build, just a tip for a box transmission, the port needs 45 degree angles at each turn (use wood), to guide the pressure wave used to prevent pressure bounce back into the t-line.
Thanks. I would not go so far as to say that it needs it, but it will surely help the flow of air. There are many highly regarded commercial designs out there that do not always implement this, and they seem to still function as intended. I get what you say though 🙂
Actually, the corner pieces are usually cut to the size to make the bend the same surface area as the line. An ideal corner piece would therefor me concave to keep the perfect surface area. :)
it sounds so nice to my years, i use EASARS Headset
Thanks
Damn... there is a logo i have not seen in years! I'll still screw up and call amd cards ATI sometimes though
ESTUVIERA GENIAL , SI TAMBIEN LLEVARA DIY AMP CLASS D SUBWOOFER AMP
This looks great! Whats the f3 of this sub and how does the driver generally perform? I'm currently planning a build using this driver so I'd love to hear your thoughts!
Thanks. The driver does well in this enclosure, and can handle quite a bit of power. It really moves a lot of air. I have not yet measured the F3, but modelled should be in the range of 35Hz or 40Hz. Perhaps I'll do a follow up video in the new year where I can do this and show some more stats.
You should offer these so people could buy them, what was the last song called in the demo?
Thank you for your knowledge Now my house is a movie theater. Because your speaker formula
Cool, thanks for watching!
Yeah I want one of these for my car hook me up!
Why? It would have barely any bass. Just get a single ten with a big ported box for deep lows
@@jaanbanaan69 can you explain further, like how does box size and design affect bass
@@jaanbanaan69 he's great too!!
im curious what the result would be if you took half the depth off from the box and shrunk the port spacing to 1/3 of its current measurement.
suffer port noise
Please give me measurement details for each wood pieces.i need same box ,I have same subwoofer,pls sir
What website calculator did you use for t line? How do you compare it to Bose bass? Since they use small subs also, prooving small can be sufficient. Nice craftsmanship!!
I used Hornresp. I have not heard any Bose products before so can't comment. Thanks!
hello please can you put the measurements thanks a greeting
Is this a constant CSA using Sd, 0.75Sd or ~ 1.5Sd maybe? and a line length of 75”-80” to f3 @40hz? Im looking for a last minute xmas solution as my other plan got foiled at the last moment ...
It's just a straight line where the mouth of the line is equal to the Sd of the driver. F3 should be around that, yes. I have the SketchUp drawing on my Patreon page.
i have a 4inch 4ohm 20w woofer from an old cheap subwoofer which i don't know the ts parameters but it plays under 40hz well free air
Can i still use this build?
To prevent damage i'll just lower the gain on my amp
Will this build work for me without knowing the ts parameters of my woofer if i dont play too loud?
what name of music did you play in the speaker pls share me
Can you do a bandpass design?,
I'm a bandpass fan
perhaps sometime in the future.
what is the title of the music you pack at the end of your video
Awesome build! What's its tuning frequency?
70 hz , the line is only 4 feet max , 35hz is 97 inches long , this is nowhere near that long , I build T lines and horn loaded speakers. This build is a joke .
awsome
Thanks
Good quality speaker but the pice is very hi for this little thing.. nice build
i wish i could build a custom enclosure for my 12 inch but i dont have those kinds of tools
Do you know where to get a good 4 inch subwoofer because my 4 inch subwoofer blew in my gaming chair and need a new one please help🙏
You should have covered the bottom air passage with black net.
And use copper binding posts instead of a cup.
boss, why is the port added a silencer? what is the function?
Can you please build a 2 inch t-line sub box?
Minimize screen to 50%
no hole saw?? great job
If only a hole saw could drill a square hole ;)
Is the inner cable also glue?
Can you plsss give the measurements
Do u have file for cnc cutting? I’d love to have one. Thank you :D
Sorry, no. I did this all manually by hand with router and tabel saw.
You can make video working this sub more long?
sebas5688654 it sounds great ☺️
Reformulated question: Would it be possible to add a mini tweeter to a 2.0-channel soundbar via serial connection, turning it into a 3.0 channel soundbar to get a better sound clarity (clear and crisp dialogues)?
I would not connect it in series, but i parallel to the drivers. It will be a bit of a hit and miss exercise though.
Please make a sub with passive radiator.
Are using a 2 way crossover for bass and mids?
06:38 What is the music name?
Can someone tell me please
for that material you put inside the sub can i use my leftover single socks. rip them up and stuff or is that a bad idea?
Ofcoures you can,recycle them..

The Tang Band W4-2089 isn't available on PartsExpress (200 min buy + 4 month lead-time). Is there another smallish driver 5-6" that has similar performance that you would recommend for a similar build (scaled up for a larger driver if necessary). Seems like most of the woofers in the 6" size have a frequency response starting at around 90Hz where the TB starts at 35Hz.
You can contact Tang Band directly and ask them if they can sell to you. tb-speaker.com/
Which tools and calculators do you use to design the transmission line and how to build it
