I have an offer to sell my 15" Kicker Solo-Baric. It's the new square design and this sucker really pounds. Do you guys think I would be happy with a 12" Kicker Solo-Baric after being used to the 15"? I never really played the 15" that loud unless I was really in the mood to jam. Just wondering if you guys have any experiance with a single 12" and 15". I don't want to regret this later and wish I still had the 15". I listen to mostly high-energy trance/techno which always has hard basslines and fast beats.
