Its been a hot minute since I've been back around the SSA Forums. So what I have to share is our new M3 lvl 6 15. http://youtu.be/LgINN67wNHs?list=UUCyrPB8lLWhPP-oWTfTP7hQ New proprietary 15in basket uses a newly tooled 10in spider. It can accomodate a full 4in peak to peak and comes in with a 28hz fs. Just what the low low tuned daily groundpounders need! In the video sub was on a 10k in a box built for 2 lol.
