To my surprise, these subs are impressive… I bought them for our home stereo system and they added the deeper bass I was looking for. Of course, with two Cerwin Vega AT-15’s, they get buried. I just placed another order for my car, with the SSL EV2.200w Amp. I’m hoping it’ll help with the low-end sound in there!All in all, these are great for the price. I would most defiantly tell a friend about these.
