Selling my pair of GSG Audio 21" Evolution subs with a Speaker power SP-12000 2 channel amp. I dreamt of having some massive subs (Well I already have a pair of 16hz ported 18" LMS ultras) and reluctantly have made the decision to sell these. I honestly have no time to enjoy them at all, and to date have not fully set them up. The Speaker power amp has never even been turned on. I only wired them up to my existing QSC amps driving the LMS ultra's. Literally moved the Ultra's out and put the Evolutions in place. No adjustments to EQ, Audyssey, or anything. I've watched a few movies with them this way, and they blew me away without optimizing them!
They are fitted with the Eminence NSW6021-6 21" tour grade driver.
