This subwoofer was designed around a down-firing Tang Band 6.5 inch subwoofer driver. It is a ported bass reflex enclosure with the port firing forward. The goal was to have a relatively small and elegant looking subwoofer that can fit into most home environments. This subwoofer can easily be integrated with a pair of stereo speakers or the sound bar project that is also available on the soundblab.net website for purchase.
The subwoofer design includes a plate amplifier that can be set to 2.1 or 0.1 output. This provides you with the ability to then use this subwoofer with any system or other amplified speakers or just set it to 2.1 and connect a pair of stereo speakers. The output of the specified plate amplifier is 30W+30W stereo, and 60W for the subwoofer channel.
When following the build plan for purchase (www.soundblab...., it can easily be built with everyday woodworking tools, and even by someone with beginner woodworking skills. The construction follows butt joints.
When following the build plan, the end result should give you a speaker that will have the following approximate specifications:
Power Output: (Mono) 60 Watts (4 Ohms)
Bass Principle: Ported or Bass Reflex with approximate -3Db of 35Hz.
Approximate Size (W x H x D): 240 mm x 400 mm x 209 mm

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.

@wesselw.7801 4 года назад

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 4 года назад

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

@bloomerb4162 Год назад

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 11 месяцев назад

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 11 месяцев назад

@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.

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

@toddedrums 4 года назад

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 4 года назад

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.

@Jan-nd1hv Год назад

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

@SoundBlab Год назад

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.

@springbokmarine 4 года назад

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

@wesselw.7801 4 года назад

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 4 года назад

@@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 4 года назад

@@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 4 года назад

@@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)

@radiospank 4 года назад

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 4 года назад

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.

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

@UhOhUmm 4 года назад

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 4 года назад

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

@SoundBlab 4 года назад

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.
