I think the set up you originally proposed would sound fantastic. Set up and placement will be the key. I personally have a much larger room with M22,vp100, M3's as surrounds and and old cht10 velodyne sub, powered by a Yamaha RXV3900. Most would say to small for a 4200 sq ft room. It sounds great for both music and movies. Definitely gets loud without straining and maintains its musicality. One thing I picked up from an article by Allen was to raise the center channel 3-5db above the front speaker settings when watching movies. Makes a huge difference. Will upgrade the velodyne at some point but it does a nice job. I guess what I am saying is you will be happy using Axiom for your set up in most configurations.
