I was not impressed with them in SPL, and the SQ is a bit over par...not a bad sub by any means, but the subs you have them up with put it to shame. I will tell you something...drop the Ti. Not worth the money. Your Alums would be as sufficient...Originally posted by denim so only one person has heard the OZ subs?, they are massive and seem like they could move a ton of air, but I am curious about SQ on them, even though i know SQ for the rest of OZ equipment is really good
