Here's my setup, keep in mind I only use this for TV/Movie watching/listening.
Cerwin-Vega VE Series bookshelf speakers (3 pair)
Cerwin-Vega VE Series Center (1)
Velodyne VRP-1200 Subwoofer
My room is 12x20x8, hard walls. I think the sound is wonderful for the purpose I bought these for. Total cost including the sub was a bit over $600.
I also considered the Venue line from JBL but my preferred supplier couldn't get me the ones I wanted in a reasonable timeframe. Also, HK has speakers and since they own JBL, you can guess who manufactures them...
