And SPL dust.
anyways...its freaking ridiculous. I need to find a way to deaden my rear wall, because even tuned as high as it is right now, the metal and the little plastic piece are going to town rattling. Overall....
Loudness-9.5/10 (loudest single12 setup ive ever heard)
SQ-5/10 Gets squirly at about 21/35 on my alpine, even with the new and improved it slaps a little, but better than the other one that slapped at 15.
box diminsions are 9 deep-15 tall-48 wide
and like justin said dual 4 inch aeros out the side and 5/8 threaded rod for bracing. plus a little love from the roundover bit and the palm sander.
