Current ownerAs for comparison I haven't owened any of the listed but have heard them in several different cars.BTL,Nightshade,and mach 5 would be alittle more SPL oriented IMO and in another class then these.However that doesn't make them any less of a sub.I say these are a good mix of SPL and SQ for the best of both.They can get loud while still being amazingly accurate with response.As for power handling I would say the 1000rms is a conservitive number.
