Okay. I am hearing loud and clear. So, it would appear my system should look like this- as recommended.

2x M22's $440
2x QS8's $500
1x VP150 $385

or around $1325 before subwoofer.

At 13 lbs, however. How do people mount the QS8's on the wall if there is no 2x4 to support it? Along my back walls (http://www.freewebs.com/epchristi/LIVING_ROOM2.jpg) there are no 2x4 stud supports where the speaker needs to be centered. Have others encountered that?

I think I am almost ready to go with the system as described and appreciate everyone's help.

I am considering the HSU sub woofers that were recommended.
