Do you just have a bandpass filter on it without eq? Do you have any acoustical measurements?

I have a Clarion Memphis 16-XO3 on them that i'm working with right now. No measurements of any kind have been done.

8s arent needed for either. Very good high excursion(9mm) 6.5s out there that do great on midbass.

info from a forum that barely manages 120-140db setups. You have some rare spl guys over there but a majority of them are the 140 and under club.
