Feedback on Sub Construction

The Grif · 9th June 2010, 11:56 AM

Hi all,

I have decided to try and build a sub as my first DIY project.

After listening to a bit of advice and recommendations on a few websites I have decided to go for a Exodus Audio Tempest-X driver with something like a Behringer EP4000 Amp and a Behringer DCX2496 to split the signal.

On reading some info on the Tempest-X, it was suggested a 200L box would be a good match and heavy bracing was recommended. So I thought something like this maybe the way to go (top, bottom and sides removed to show bracing). Its approx. 70cm(H)x50cm(W)x60cm(D).

Any feedback welcome.

I hope you don't plan on moving it often. It must weigh a ton when finished!

Total, complete bracing overkill unless you're making it out of balsa wood, but since it's already done, carry on............

Like GM said, overkill.

I don't suppose you have a few hundred 5" drivers you could mount in there? I assume they're 5", but it would give interesting dispersion.

Must have been funny to compute the final volume inside the box ... to match it with the speaker.

Nothing wrong with overkill!!

What driver are you using, RDX or Amatol

I'll be using the Exodus Audio Tempest 15" driver and powering it with a Behringer EP4000.

I just need to pull the finger out and finish the outer cabinet.

Oh my god,you are a trooper. That is awe inspiring! Maybe try concrete next time

You obviously have never "Blown" things up for a living have you??
Both are extremely brissant explosives .

I hope the walls are going to be of the same quality as the bracing; 25mm marine plywood and 32mm MDF glued together should do it, again nothing like overkill.
Seriously tho 2 layers; 12mmMDF and 16mm marine ply wood glued together would be ( pardon the punny) extremely rigid and dead
