I picked up a tdx 15 dual voice coil 2 ohm for $100 in a pre-fab box. 1200 watts rms. Hooked it up and found out the box is broke. It sounded like Donald Duck getting kicked in the nads.

I would like to build an spl box for it but after googling my fingers off I can't seem to find any box spec recommendations. I was hoping to find a simple slot port build or something because I am still a noob and don't quite understand the Qs's and the other mysterious letter number references on the tech sheets

Any ideas or opinions would be appreciated. I prefer spl over sq.

Do you have the T/S parameters handy? It would help people get some ideas together.

Here goes. Not sure what it means, I hope the t/s's are in there. But as far as box building goes I'm a carpenter and understand dimensions and building techniques.

Diamond audio mailed this to me after I posted. So they recommend 1.65 cubic but I doubt thats optimum for spl.
