Good morning, I wanted to know if it was possible to buy the subwoofer of the video, that is, already fully assembled and red. Color is important, as I should combine it with the speakers that I already have and which are precisely red. If possible to buy it I would be interested to know the final price, including shipping costs, I live in Italy. I await welcome feedback Thank you Best regards Simone
SoundBlab I did enquire sometime ago and wanted to purchase on commercial quantities as we run a car audio business. We wanted to develop innovative speaker systems which would have knocked a lot of socks off, but they refused us because the quantities were not high enough. I still have the designs, but no cooperation...
Tang Bang if you're reading this you need to get with a company and make a complete kit with knockdown box for those of us too lazy, too busy, or too dumb to do it all by ourselves!!
I do like the *(Whole Kit Idea). It could be in simple wood, & or some plastic parts. So the user - us. Could pain it to our heart's desire. Awesome video.
A long time ago I bought a little inexpensive 2.1 sound system meant to connect to your TV or video game console. I believe it has a three (3) inch woofer but the box was a pretty decent size ( relative to the woofer that is) I was impressed with the amount of bass that it gave off. It was actually great for a bedroom. It probably better suited for a desktop computer setting though.
I didn't come here for the tutorial, I don't have professional grade tools I came here for the entertainment in watching snug fit assembly and rounded edges. And 33Hz bass.
Same with my sound system. There is lots of bass with the littlelest movement from the sub. Really efficient driver i guess. 6.5" 220w unit. Sl8yg soundbar btw
I have a little space under the rear seats of my truck. I really want to make a slim box that would use a couple of these drivers. I don't need crazy levels of bass, just need to fill in the flat sound in my truck now.
I’ve no access to wood tools, while I’ve an FDM as well (and potantially a glowforge laser cutter 42W)... Might you share the project? Would the plastic enclosure sound well? Any material sounds differently...
Watching you build this, really makes me wish i made a 2.1 speaker set for a project at school rather than a hifi cabinet that i did. I didnt dream big enough.
HA! unfortunately im in my 30s now and dont possess the tools or access to a workshop that would allow me to make such things! After leaving school i went to college to study IT but left carpentry as a backup option as I enjoyed that a hell of a lot and was half decent at it. I never did get to studying carpentry as i spent too many years reading the books for IT. Its never to late to learn but time and money is not something i have huge amounts of 😜 Its the path that i have chosen
I really like your build, especially that you make enclosure between AMP and SUBs by MDF pannel. Saw that very rarelly, even for huge subs. Even pro audio companies like Genelec ignores that, at least in their aluminium monitors.
A reason the amp is not separate is to allow cooling of the amp components. If you notice, most manufactured subs will have a port near the amp so the air cools the amp as it passes. This option becomes dangerous for high volume continuous loads as their is zero cooling for the amp without external heatsinks. Of course in theory, a separate encloser can reduce vibration to components, but in all reality, with enough volume it's better to have cooling then run components near the solder melting point or glue melting point and still have vibration regardless of separation. Plus you loose less volume without the separate encloser as well, and in many cases, size does matter for locations.
Nice build! I'm gonna be building a ported Bluetooth soundbar and was planning on using this subwoofer. I'm excited to build it and can't wait to hear it! Very impressive specs for only a 4.5-inch driver!
You probably want to use some calking on all the inside joints, and gaskets on the driver/radiator. Experiment with some Polyfill and you might get even better output as well.
My glue joints seem to be holding up well, but extra calking should not hurt. The PR and driver both have gaskets already attached. Maybe it was not clear in the video. I still want to experiment with polyfill and extra weight on the PR.
i wonder how 3 of theese, one 4" midrange and a tweeter would fare in a taller floorstanding speaker? kind of like the system audio Ranger's i once had, those speakers went DEEP and was "punched in the gut quick" with ultra long throw 4" speakers. jawdropping speakers tbh, hate the fact i sold them.
Nice, new subscriber here. No idea if it's possible, however I believe I would have explored placing the passive radiator on the bottom ... assuring adequate clearance etc.
Hi, welcome! That is certainly an option. Although, some drivers and PRs have shown a tendency to sag when mounted on the bottom of an enclosure. Personally however, I have not experienced this so far in any of my builds with bottom mount drivers.
Cute sub, and your workmanship is so excellent! I hate to say anything negative.....but.... its a 4" driver. I bet it sounds impressive at low volumes, but I really doubt it would satisfy a lot of us who like to turn up the tunes once in a while. For similar pricing you could drive a low cost tpa3116 class d sub amp (100w@2ohms) into a dual 6 or 8" ported sub at and get some real chest pounding bass. I am currently playing with different designs and am finding a single 8" subwoofer insufficient for my pc setup in a somewhat average bedroom - again just for the odd time i want to crank up the tunes to higher volumes. Moving up to a compact 10" or dual 8" or maybe a 12" even...nothing beats the displacement of a larger driver. I am looking forward to your sound test though - maybe i'll be pleasantly surprised and proven wrong lol.
Thanks man! Sure, I hear you. However, the size is a bonus if you are looking for something this small. Any 6 or 8 inch driver will require a much larger enclosure. I suppose it depends on your needs at the end of the day.
YES!!!! Radiator builds are fantastic and adjusting the weight of the radiator can make quick changes. EarthQuake Audio has perfected this technology very well. responses are great but amplitude is key ;-)
Excelente trabajo tenia tiempo que no veía un bafle con radiador pasivo,este sistema tiene una producción de frecuencias por debajo del mismo subwoofer y tiene gran fidelidad,saludos...
This popped into my recommended feed and I immediately recognised your accent. Loved the build and would like to try something like this, wonder how it will compare to my PSB Subseries 100. Cheers from another Cape Townian.
A passive radiator acts very similar to a bass port. It is tuned to a specific frequency, same as a bass port, but it eliminates the typical noise that is associated with a bass port.
Nice! Been looking into building a compact sub and your stuff comes up a lot. This was really enjoyable. The super thick frame must play into how deep the driver goes, but how I wonder? Does it seal better? Is it just the added rigidity?
This driver also has a double surround. There is another surround on the inside behind the front surround you can't see. Also a very beefy magnet. The driver frame is also very solidly built. Small, but powerful and well made.
Are nails and glue really necessary for the template. Dont get me wrong I like to glue things my favorite is ca and accelerator especially for when I cut myself working
Mind aswell just mount a nonpowered fan that size into it as a port for the air / wind from the bass. That would be cool to add. Instead of a rounded/tubed port, or a vented. A regular small nonpowered fan would be cool to use. The wind / air from bass will move the fan.
Awesome job. I'd like building one up, but... I'm short of wood tools... But I've both FDM and Resin printers, and can access a 42W laser cutter, therefore I'd like a lot to find a project that uses digital fabrication "facilities". Hasn't anyone done this, yet? Thanks
That is totally awesome but cutting out those non circular speaker and radiator cutouts takes some router skills. Using a router is not as easy as it looks I have f-ed up a lot of wood learning how to use one. I am impressed with jig he built as I was wondering how did those perfect cutouts. I would still end up wasting an entire sheet of mdf to build this little guy.
When will people remember that a woofer reproduces relatively flat down to 30Htz whereas a Subwoofer should be reproducing down 1/2 to 1 octave lower, typically 15 to 20Hz? My Bass guitar plays down to 15Hz and only uses 10inch "woofers" in a ported cabinet. Keep up the good construction videos!!!!
Wrong. Sub bass frequencies start at 60Hz and go down to 20Hz, 20 being our sonic threshold. Anything below that is only felt, not heard. So what you are referring to as a 'woofer' that plays 'flat down to 30hz' would still be called a SUBwoofer as it's playing the aforementioned SUB bass frequencies. If the bass frequency of a particular speaker rolled off at 50 or 60 Hz then THAT would be generally called a mere woofer. Here's an article - www.teachmeaudio.com/mixing/techniques/audio-spectrum
Thanks you! I think this 'small subwoofer' is probably a good option if you have smaller desktop speakers that can'y go as low as 30Hz, but cut off in effective response after 50 to 60Hz. Then this will be perfect to fill in the lower registers to give a fuller sound.
Not in this one, but it will not hurt to include some. The cabinet is bery small though and I did not want to obstruct the movement of the passive radiators with internal damping material.
Excellent build would like to have 2 or 4 of these Subs in a soundbar. And bass box for a hatchback. Need slim looking boxes. Guess 4 tang band could be equivalent to a 10”
All you have to do is add up the surface area of the cone and find a larger single subwoofer with the equivalent surface area. That will give you a rough idea of whether they will move the same amount of air.
Well they are 4" speakers, two would be the equivilant of a 8". I think you would hear the bass more than feel it. It is a good idea if one is concerned about packaging and fitment. I imagine these are fast moving subs and could be used to assist one or two bigger woofers or subwoofers. I can imagine some sick sounds, keeping these with the passive radiators, and including some bigger woofers and subs in appropriate sealed and ported boxes.
I have to say this is a very nice build. Simple, but nice. I don't understand this passive radiator though. No diaphragm? It's not really much of a radiator then. Woofer´s really impressive though, 8mm Xmax at 4 inches of diameter? Wow. The only problem with this is that it would need a lot of power.
Actually the impedance curve is also important to show, there you can see the real resonance of the woofer. With this small woofer would be better they use many small neodymium magnets so can more space for air go around the magnets. I would honestly try change the magnets or atleast make bigger whole in the centre of the magnet pole
Hi there, this is sweet! I'm from South Africa- sounds like you too! I'm wondering the best way to ship or buy a small subwoofer like this locally? I bought a TPA3116D2 and i'm looking for a small subwoofer to match. i.e.100wrms with low frequencies.
interesting... shame we cannot listen the same through the other side of the screen (things like mic, encoding, playback setup, etc. counts). I listen to much BRRRRRRRR but at 19:00 starts to sound better! With this size you can do 2, 3 o 4 to place anywhere lol
I have been wondering why certain speakers have that... I don't know what to call it... lung type thing. Like the purpose it serves and is it an alternative to a port. I've researched building sound equipment and whatnot and have only started seeing those lung things recently. Does it increase sound or air pressure?
It is called a passive radiator. It acts similar to a port. A port is tuned to a specific frequency, and a passive radiator as well. The advantage is that you do not get the potential air chuffing noises that a port can produce with a passive radiator. This is a very basic explanation, but I hope you understand the concept.
Unfortunately I bought the driver (W5-2053) on it's own. Then found out that the passive radiators I bought to use with it required massive lead weights and still weren't tuning quite right. Apparently Tang Band won't sell you just the passive radiators, either. So I was fucked. I just got done building a ported box for it, and it still plays down to 32 or 33 pretty usably. 35hz is solid. This isn't crazy loud, and won't shake the room, but it complements the 3" rear loaded horn speakers I built from Tang Band's plans.
I don't think you'll get much smaller than a long throw 12inch driver in a 400mm square enclosure, but then you will need to add some servo control and DSP to get down to 20Hz.
@@SoundBlab looking at maybe building something DIY, maybe dayton ultimax box with 50cm width, 50cm-60cm height and 40cm depth. It wont be a small box, but since it wont be as deep as for instance klipsch 15" I could then up the volume for an 18" driver. Or maybe I should put it in infinity baffle in ceiling.. Havent decided yet, still looking into this. I tested an Thor IWS 10" with passive woofer, but I couldnt get it below 30 Hz in a frequency sweep.
As impressive as the graph is and how low it goes for its size, its probably not going to have the excursion at that size to produce meaningful low bass to compliment anything but the tinniest of desktop speakers for a computer. Having stepped up to a 6.5" TB subwoofer would have been better as it would easily be twice to 3x the output. Sure its bigger, but its a more usable project then. It is a very nice build though. Great wood working.
Thank you! It is a sanding sealer that is painted on in a few layers and then sanded in between. It seals the MDF so that it does not absorb the spray paint for a better finish.
You can get this driver and passive radiator bundle by contacting Tang Band directly through their website at www.tb-speaker.com
They will reply if you make an enquiry.

I like how you used the CA glue with a quick spray of accelerator on the opposite piece for initial attachment.
Cool trick!
That stuff is amazing I use it for woodworking as well
Also the red-black for this subwoofer is dope!
Thanks
The last touch: Stick a round "dB" logo on the middle of the passive radiator.
I also like the wet sand on the coat of spray paint. I hadn't thought that would make it shine like that, but turned out nice!
Thanks man! If I had more time I could do more paint layers and wet sanding for an even better finish, but time is money...

It would be nice if a similar effect could be achieved by making the enclosure with a shallow depth while maintaining the cabinet volume at 3L.
I have a little space under the rear seats of my truck. I really want to make a slim box that would use a couple of these drivers. I don't need crazy levels of bass, just need to fill in the flat sound in my truck now.
Seriously considering getting the drivers, modeling the suggested box, and printing it on my Creality CR-10. Could be a fun project!
Yeah, think thats a great idea!

Less resonance because of the added rigidity

I don't understand this passive radiator though. No diaphragm? It's not really much of a radiator then. Woofer´s really impressive though, 8mm Xmax at 4 inches of diameter? Wow. The only problem with this is that it would need a lot of power.
Tx. Yes, the driver is not very sensitive, so you need a powerful amp to drive it.
How did it sound?
Can we make this for car audio?
Actually the impedance curve is also important to show, there you can see the real resonance of the woofer.
With this small woofer would be better they use many small neodymium magnets so can more space for air go around the magnets. I would honestly try change the magnets or atleast make bigger whole in the centre of the magnet pole
Your suggestions aren’t even valid. They’re utterly pointless.
Great build, great video... but sadly your mic cannot capture low end note..
Thank you! It sounds fine when I listen to it. Perhaps upgrade your system.
My speaker clearly can’t play it!
Maybe because of the -9 db on 30 hz of the subwoofer
No Bass here either. Using a good sub here which normally produces low frequencies well on UA-cam.
how is it wired to the amp and other speakers?
very beautiful
Thank you!
Hi there, this is sweet! I'm from South Africa- sounds like you too! I'm wondering the best way to ship or buy a small subwoofer like this locally? I bought a TPA3116D2 and i'm looking for a small subwoofer to match. i.e.100wrms with low frequencies.
Hi, there are no local options. You will have to import. Parts Express, Madisound Speaker Store or Soundimports.eu
Great idea for the template, thanks.
Cool!
One thing about it, the bass should be fast enough even if it isn't loud enough. Need a line array of about 10 of these on each side.
interesting... shame we cannot listen the same through the other side of the screen (things like mic, encoding, playback setup, etc. counts).
I listen to much BRRRRRRRR but at 19:00 starts to sound better! With this size you can do 2, 3 o 4 to place anywhere lol
I have been wondering why certain speakers have that... I don't know what to call it... lung type thing. Like the purpose it serves and is it an alternative to a port. I've researched building sound equipment and whatnot and have only started seeing those lung things recently. Does it increase sound or air pressure?
It is called a passive radiator. It acts similar to a port. A port is tuned to a specific frequency, and a passive radiator as well. The advantage is that you do not get the potential air chuffing noises that a port can produce with a passive radiator. This is a very basic explanation, but I hope you understand the concept.
@@SoundBlab I get it.
Unfortunately I bought the driver (W5-2053) on it's own. Then found out that the passive radiators I bought to use with it required massive lead weights and still weren't tuning quite right.
Apparently Tang Band won't sell you just the passive radiators, either. So I was fucked.
I just got done building a ported box for it, and it still plays down to 32 or 33 pretty usably. 35hz is solid.
This isn't crazy loud, and won't shake the room, but it complements the 3" rear loaded horn speakers I built from Tang Band's plans.
Yeah bummer that they only sell it as a bundle! Glad you made it work though!
I wonder if the sound quality would improve if you fill the inside of the speaker with small polystyrene balls as they do on smartphone speakers.
suman .P just cotton wool would do
How compact could one make a sub that goes in the 20hz range?
Maybe a bit larger driver, but horizontal subwoofer of good quality?
I don't think you'll get much smaller than a long throw 12inch driver in a 400mm square enclosure, but then you will need to add some servo control and DSP to get down to 20Hz.
@@SoundBlab looking at maybe building something DIY, maybe dayton ultimax box with 50cm width, 50cm-60cm height and 40cm depth. It wont be a small box, but since it wont be as deep as for instance klipsch 15" I could then up the volume for an 18" driver. Or maybe I should put it in infinity baffle in ceiling.. Havent decided yet, still looking into this. I tested an Thor IWS 10" with passive woofer, but I couldnt get it below 30 Hz in a frequency sweep.
As impressive as the graph is and how low it goes for its size, its probably not going to have the excursion at that size to produce meaningful low bass to compliment anything but the tinniest of desktop speakers for a computer. Having stepped up to a 6.5" TB subwoofer would have been better as it would easily be twice to 3x the output. Sure its bigger, but its a more usable project then. It is a very nice build though. Great wood working.

Hi! Very nice build! What did you use as mdf filler? That transparent stuff...
Thank you! It is a sanding sealer that is painted on in a few layers and then sanded in between. It seals the MDF so that it does not absorb the spray paint for a better finish.
Nice work!
Thanks
Really cool! Are you able to measure the response to see if its up to the specs?
Thanks! If I have time I can do that and give a performance report at some point.
