first off my entire home theater setup is JBL, so when buying a subwoofer for my pontiac i stumbled upon this for 80 bucksi have to say these probably beat a pair of kenwoods or pioneers at the same wattage rating, because of the fact that the motor on this thing is actually pretty monstrous. it gets nice xmax, and it just looks flatout better than any other sub in its class,if only t had more wattage, then it would probably be a much better subwoofer. as for people who arent looking for something that will compete with 15'' MOFO's, this will do it quite nicely...
