Tips & Tricks:
cut all the pieces accurately. this is more complicated than a ported box and the pieces have to be precise.
i couldnt be more happy with this sub, not boomy at all. ive thrown everything i have at it from jimi hendrix to some old school bass testers just to see what it could do. it can play it all with ease.
