this sub has NEVER BEEN USED. my stepdad got it for me as a gift, also, the user bernymac told me he saw three of the 15 inch CSP's do 162 DB's. ofcourse the CSP 15 is the little brother to this sub, the CSP 18.i have went to the concept audio website and gives specs for the CSP 15 but not the 18. i went to a concept dealer about an hour away and he told me that it was a prototype sub and the 15 was the only in full production. this is about all the info i have on this sub, IM me trey4sports on AIM or PM me on here. i will listen to reasonable offers and CONSIDER TRADES! in paticular im looking for JL W6's or 1500W rms amp
