[QUOTE="mat3833, post: 8751253, member: 587645"] The level 4s are definitely nice. But if you look at a Dayton HO 15 they have virtually the same Xmax, a much lower Fs, and higher sensitivity, all with a 2.5" coil. That adds up to a woofer that gets just as loud on half the power and weighs 30 pounds shipped. Edit, the DC woofers will definitely be louder when driving a port. As I understand it higher RMS woofers can generate more cone force which can be translated into output through driving a port or passive radiator. Without that port output the Dayton would be just as loud from my somewhat limited experience. The DC will get louder in a ported enclosure since it has the extra thermal capacity and can drive a port. But the Dayton will sound better and get just as loud on less power in a sealed or 4th order. There is more to a sub than power handling and cone area. If you just want to get loud, go for the most come area with the beefiest coil you can afford and throw it in a big ported enclosure. If you want to sound good and get loud, you have to look deeper than RMS and cone area. Matt [/QUOTE]
