I have had a system with the Infinity Primus 360's, 150's, C25 & PS12. Very good sounding system. I did swap out the sub for a Dayton 15" due to the size of my room. (24 x 28'). The PS12 still does a fine job in my 14 x 18 bedroom though. Hard to say which has a "better" sound. The 15" is louder for sure.
