I am part of team image dynamics and i am very picky on equipment. Two 12" idmaxs gave me loudest in state and 145+ db(new termlab). The IDmaxs are great, easy to recone and can take a beating. If you are looking for SQ, they are excell there even more then the SPL. At SBN, i sat in some of the ID cars and they sound excellent. I would recomand them to anyone.
