There are a few that have them if I am not mistaken. I know for a fact that PESTEELE from here has one and likes it and dont like it. Says it bottoms out or something rather. So might want to ask him. Orrrrrrrr, go to Soundsolutions.com and hit up the Fi forum there. Good luck.i know...does anyone here own an 18" Q and know what it sounds like...and what i should tune too??
anyone else maybe wanna design / build a box for it?
