The BUILD PLANS for this project can be purchased here: bit.ly/30u4d5a . It includes a comprehensive 28 page description of materials, parts, etc. on how to build this subwoofer from beginning to end.

[@jimthvac100]

I became a subscriber when I watched your video on the DIY Ported Subwoofer Build. Very impressed with the use of the router. You make beautiful speaker cabinets. I like the soft edges of the majority of your cabinets as they will resist chipping. Your speakers sound good too. I also was not aware of these miniplate amplifier/crossover boards that you install in some of your subwoofers, So I am grateful for the knowledge of them.

[@SoundBlab]

Thank you very much!

[@msmith2961]

The perfectionist in me wanted the amp plate to be flushed into the panel.. Great build though and looking forward to part 2!

What ended up being the final frequency response of this subwoofer?

[@wesselw.7801]

Very solid and clean build. Your woodworking is really sophisticated and delicate. Got a question tho, what software do you use to calculate your enclosure and port size? Looking forward to the soundbar build. Thx for the extra effort of filming your creations and posting them on yt :)

[@SoundBlab]

Thanks. I used WinISD to determine the enclosure and port size.

Plz tell me the dimentions of sealed enclosure box for one 12 inch, 2000 watts rms sub woofer ?

[@Tonygarz]

I wonder if it would of made a difference if he turned it into a 4th order box with that bass radiator facing the ground when sub box sitting right side up probably would of gave it some extra low sounds either way great build my dude 👍

[@modernbassheads5051]

4th orders don’t magically play lower than bass reflex boxes… dunno where you’re getting your information from bro

[@ximonx]

Quick tip: don't solder wire ends that are going into solder terminals, the solder can migrate and you'll end up with loose wires 👍

[@SynZ777]

I've been wiring pots like that for years and I haven't had an issue with it.

[@FreshLeaves]

@SoundBlab Will it make any difference if I switch the position of the sub from bottom to the front and using the same enclosure dimension?

[@SoundBlab]

You can do that. It will perform the same.

[@SoundBlab]

[@BungToba]

O master please take me as your apprentice. You're so skillfull in woodworking!

[@krisandersson7156]

Cool build but that port looks dangerously small. Port Noise?

[@toddedrums]

For a 6.5" driver that seems like enough port area, it is fairly wide. And it also probably helps achieve a lower port tuning.

[@SoundBlab]

It actually does not create any port noise, even at full volume. I made sure to look at this when I was modelling the enclosure in software.

[@bloomerb4162]

I'm interested in building a 6.5 sub enclosure for the best sound quality. Tight bass, no boomy sounding bass. Would it just come down to how rigid the enclosure is?

[@SoundBlab]

A rigid enclosure is critical for a subwoofer, however the enclosure must also be designed and modelled well with software. Too small and it can be come boomy at higher low frequencies, and also limit the output at the lower end. Too big and you can again loose output at the lower end. The size of the vent, if going with a bass reflex enclosure is also going to determine the outcome. Too small of a vent can cause port chuffing as the air moves through it. So there are many factors to consider for a good subwoofer enclosure design.

[@bloomerb4162]

@SoundBlab after all those factors are taken into account, then rigidity? I've always heard the more rigid you can get the enclosure, the better or tighter the bass will be.

[@piotrekhunt2440]

what software do you use to create such cool stuff?

[@Acoustic_Theory]

Another day, and another 6.5" Tang Band project. We need some new tiny subs, and the Tang Band subs leave some big shoes for any new driver design to fill.

[@SoundBlab]

Yeah for sure. I would love to see another manufacturer come to the table here.

[@adamdjd7882]

How does the sub plug into the arylic? I've bought plans for the soundbar design, but already have a sub to use Thanks mate

[@SoundBlab]

I use the line output from the Arylic to plug into the sub, which is a 2.1 plate amp.

[@adamdjd7882]

@@SoundBlab thanks for getting back so fast, by line out are you referring to speaker cables that run to the subwoofer or is there an RCA connection that I can't see on the board? ( as that's what I'm used to connecting a subwoofer with. )

[@mje3055]

you're the man

[@SoundBlab]

Thanks!

[@springbokmarine]

Great video! Does the Amp need more ventilation? It seems that there’s no airflow around the electronics.

[@wesselw.7801]

I agree that normally a bit of ventilation would be usefull. However, I feel like this amp is not likely to overheat any time soon, since it is a highly efficient and relatively low power class D amp. I reccon that the little heat the amp might generate, will not be enough to cause any issues. Furthermore, the chip will also be cooled by the aluminium backplate.

[@p_mouse8676]

@@wesselw.7801 unfortunately I have seen the opposite from a lot of people with this particular amp. It overheats very quickly. Not very reliable.

[@wesselw.7801]

@@p_mouse8676 Are you certain that they had the amplifier setup correctly? The chip has an efficiency of 90% which makes it put out very little heat if it is used correctly. It seems to be quite an uncommon issue in online reviews so it might be possible that it was setup incorrectly, maybe a lower than 4 ohm impedance. If not, maybe they got a faulty one?

[@p_mouse8676]

@@wesselw.7801 They had the amp running free air even. And 90% seems a lot, but that is still not 100%. More over, the PCB design is just really poor, and mostly the inductors on it are WAY to small. (I design amplifiers myself fyi)

[@wesselw.7801]

@@p_mouse8676 Hmm, well will see of the amp holds up in this configuration :b. Btw cool that you are designing amplifiers :). If I might ask, what is your opinion about the kab250v3 and the dspb250 from dayton audio? I reccon they are cool little boards, but do you have any knowledge about any flaws?

[@dieselsmiths]

Oh that sounded great?

[@Jan-nd1hv]

May i ask yoou what the function of the white cotton mesh you put inside?

[@SoundBlab]

It's a damping material that helps to break up any standing waves that we get inside the enclosure. It also reduces sound waves reflecting back onto the back of the woofer cone. All this helps to 'clean-up' the sound coming from the subwoofer.

[@Jan-nd1hv]

@@SoundBlab Got it, so its let us to hear the 'solid' or 'pure' sound that came out from the cone

[@wolf-dietermanzke9233]

It has a 12v power socket on the back of the plate amp. It connects to an external power supply.

[@manjulwalia1995]

bro amazing build :) ... i watch all your videos .. specially the entire video without any skip when you use great music in the background... by the way , the sanding sealer you used , was it water based , oil based or laquer based ? also how many coats you applied ?

[@sachinzachy]

Pls tell me, is a 5 inch sub is good for making a home theatre

[@UhOhUmm]

The smaller it is the worse it is. You generally want your subwoofer to only produce sound up to 80-100Hz because then it's hard to tell where the sound is coming from. 5 inch sub is very small and it will be making sounds when you don't want your sub to make any sound, like males with deep voices speaking. For home theatre speakers 6.5 inch subs with sound bars are the bare minimum I would go to and even those are often borderline. My bookshelf speakers have 6.5 inch midrange drivers for example and I have 10 inch sub to match them, which is still considered small in home theatre standards.

[@sachinzachy]

@@UhOhUmm thanks for your words, opinion from an experienced person is more helpful to me

[@SoundBlab]

If you have small speakers or even a sound bar to pair it with in a very small room you could get away with it, but generally I would not recommend it. Would be better if you still want to go that way, is to use two 5 inch drivers not just one. A 5 inch driver will also not give you much output below 35Hz. So it all depends on the application.

[@radiospank]

Seemed unnecessarily complicated for a sub box. Could’ve used 3/4 inch plywood and skipped internal bracing. Also that port looked super tiny, what velocity is that pushing at max volume?

[@SoundBlab]

Of course you can use a thicker material, but bracing eliminates the need for that. Even with 3/4 inch I still think bracing will be a good idea. The port was modelled to avoid any chuffing that might occur at higher volumes. You can pump this to its max, and still not hear any chuffing from the port.

[@__-fm5qv]

@@BUZDRIFT Well the 5.25" version I have is playing down to 37hz at -3db. These drivers are pretty much exclusively designed to go deep, but at the sacrifice of overall sensitivity and some reponsiveness/tightness.
