SPL setup

[bdufner 0]

Wondering on box size for strict SPL setup. Would it be best to use the 3 or 5 cubic foot box or some other size. Tuning will be 54 hz. Not sure on port size yet but thinking 150" per sub if I use the 5 cubic foot size and 90 on the 3 cubic foot size. Will be running 2 Sundown Audio SAZ-3000D to each sub off a 16 volt system. Willing to listen to suggestions.

All you can do is test.

Theres no surefire way to know what is loud for your setup until u build and test.
