No way to test it at home

... but i was able to test them with the same music and movies .... amazingly the Prime towers seemed to me way better then the B&W ... i though i was mistaken , that is impossible SVS can do some better product then B&W then i read several forums and seems i am not the only one who would have pick SVS (clearly compared those 2 models only )
so i made up my mind to buy the whole set from SVS .. even the center, now that i used the same movie the that isn't much difference compared the JBL .

thanks for the support ... my next topic will be cables ...
