So I built this box 2 weeks ago for a friend. Drove to IL from NC to meet him (hes an xbox friend Ive known for a few years) and built it while I was there. 2 Zv3 18s wired to 1/2 ohm on a lanzar opti 2k or a sundown 3k.
Box specs are 8.9 cubic feet (after port, subs, wood, 45s, errthang) with 15sq inches of port per cube, port is 30" x 4.5" x 25" long. Tuned to 34.
Got it playing and it wont play anything below 45. Unloads BAD. Makes a terrible noise.
I assume the port mouth is too close to the subs. How can they fix this? Im not there anymore to work on it, but I want them to retain this box but just modify it somehow because I built the shit out of it. Braced all to hell and back, rounded port, 45s.. flush mount.. Any ideas? I have a few but want to hear others first
It's better to keep your mouth shut and give the impression that you're stupid, than to open it, and remove all doubt.
Mistakes are how you learn; try not to learn too much at any one time.
