My Paradigm Titans get rather compressed when I'm listening to anything with a lot of deep bass, so I'm in the market for something new. I've been looking at the Athena F2.2s, the Energy C5s, the PSB Image towers, and various others from Paradigm. My main requirement is fast, uncompressed bass that goes down to about 40 or 50 Hz; smooth, well-controlled (or even slightly depressed) treble would also be nice, as would a large soundstage. Imaging is an afterthought. The room they'll be going in is 12x14 with an 11 foot ceiling and carpet, and they'll be driven by a NAD C320BEE. I'll be listening to a lot of different music, mostly metal and jazz. It will be difficult for me to try out anything, but I will try. Smaller is better, and appearance very important. A sub would be a last resort, but not completely out of the question.
