Help with tdx or D9

Hey, i have a friend who is getting two d9's, and i was wondering about the box design from the website. Does it look ok? The enclosure forum was pretty much zero help.

This box seems too small, but i talked to someone that used to work for tech support at diamond, and he said this was the best for the subs.

Would it be better to do a 3.8net at 34 with a shared chamber and one 3" slot port?

What does the question have to do with TDX's?

I thought they were slightly different. My bad.

sad that we can have 5 pages of crap talk about how to blow a sub, but no one can help in a real question

Well the links aren't working for me (the site isn't working for me either), but I'm guessing its the 1 cube per chamber tuned to 40 hz (that is if its the 12" version). I wouldn't suggest those enclosures as they are tuned really high, and don't have much space. If you could give the T/S specs for the woofer (along with size of woofer) and max dimensions for the car I'm sure I can get you a design that won't sound terrible. Good luck,

I used to own this sub, great sub, 2.4 @ 30 hz for a 12" Don't use the spec from the website. Tuning at 40hz will sound like shit! Thats geared towards SPL. and a 3" port for 2 12" will not work unless you want mad turbulence.
