Let me say I started with one of these at 1st becus I'm a jl audio man to heart, but jl's are becoming so exspensive now a days. I was truly amazed at the sound of one of these 12's. So I ordered another and hooked it up and I just had to have another. Yes 3 12's in a sealed box and have not been let down yet. By me in a jl audio man to heart these subs are powered by no other than jl/ series amp. If I told you the watts you wouldn't believe me so need for the negvtive feed back. Bottom line you will be very impressed by this product. The only thing is that I think the (rms) watts are not accurate but still holds enough.
