Great speaker i own two my self with a Pro Bass box with that old 4000 watt Boss amp and they are awesome people think i have way more than whats really there. The best part about this speaker is that any part of it is fixable by just unscrewing it even the voice coil witch i found out was just 60 bucks. so basically the amount you pay for them is kinda worth it i mean i think i could have gotten some cheap 18's for the same price but in my book this speaker was worth my time and money to get it right
