I am looking for a sub $1500 speaker system. I am considering nOrh, the 4.0 video system, or maybe a pair of 5.2 prizms with a 4.1 prizm. I plain on buying a seperate sub. My question is about the sound performance difference between the prizms and the drums. Does one sound "better" than the other? I see the prizms have a deeper bass. I wish I could just go listen to them and make my own opinion. Thanks for your opinions.
