I have the SVS PB-12 in a room that is 22X12 and it is fantastic. Bass is tight and very powerful. It sounds and FEELS great. If you have the floor space, you will not be disappointed. I heard the PDR-12, and it does sound very good, but I couldn't really FEEL it.
I see nothing wrong with going with the Cinema ADP's, and the Mini-Monitors sound very good for the $$, although if you can swing another $170, the Monitor 5's sound fantastic - better than the floorstanding 7's and above in my opinion. I like the Mini's over the 3's though - better midrange and although not as much bass, that is what subs are for!
Definitely go with the CC370.
