DIY Sub

[steviej233]

So i am thinking of building a sub from scratch, any suggestions of materials or websites with helpful links?

This looks pretty cool:

I found that a coupled cavity worked really well for me. I would also look on Diyaudio at the Tapped Horn Sub thread. I would love to build one of these. Said to have great response for such a simple cabinet.

I used to have a relatively cheap but very powerful SVS sub. Yes, it worked but it was never inconspicuous, huffing and puffing in the background. The difference with my DD15 is very significant as it is tuned through a microphone and on screen display to suit the room.
I would imagine that achieving the same by the DIY route would be tricky.

Yea, it's trial and error. You can pick up a sub speaker pretty cheaply, and with MDF for the enclosure, if you are so minded, experiment away.

I find that two subs, one in phase and one out of phase works best (subject to fine tuning)

Yep, second that on the Tapped Horn. Have heard one at the last Owston. Very good indeed, no overhang that I noticed. Well worth a go IMHO.

Thanks chaps, thats something to get me started, i have a driver in mind that i am going to try and i have built a basic enclosure before so this time i will apply a bit more thought and to the design and then get building! I am running a Sony STR DA2400ES amp will the amp plates that have been suggested work OK with this? Sorry chaps still new to all of this...

Before you buy any drive unit, make sure you consider exactly what type of enclosure you are going to build ;)

If you haven't built a speaker or subwoofer previously I'd suggest you stick to something fairly easy like a sealed box. If you feel a little more adventurous then consider a bass reflex or even a 4th order bandpass (coupled cavity).

Loads of people make the big mistake of buying a driver & then finding out it needs a monster box to make it work. Decide what you want to do first & then look for a driver with the right kind of specifications!

That'll be me then:doh:
I ended up jacking the whole DIY thing in because I bought the wrong bass drivers..

It happens to the best of us... It did me to, until I learn't my lesson :donk:

I have a Coupled Cavity Handbook (well it's about a 20 page leaflet) that I could send you to have a read of. They are very easy to build:)

Guesswork will get you nowhere. Follow an established design. If there isn't an established design for the driver you have selected and you don't know how to do the calculations from the driver's T/S Params then don't bother. Choose something else. Having said that, the design formulae for closed boxes are not that hard to follow if you can cope with a little algebra.

How serious are you?

Tapped horns / pair of all the way.
Same foot print as a sub but taller.
Play effortlessly from 20Hz to 100Hz, you can cross lower if wanted.
4th order 24dB/oct works a treat.

Lots of plans out there and model first with driver in Hornresp is good idea / fun.
