I have heard many great things about Axiom speakers. I'm looking to upgrade my speakers. My room is about 22ft wide by 28ft deep. The viewing area is about 16' wide x 14' deep with an open area behind it. This is a basement with carpet and 8' walls all plastered including the ceiling. I am all set for a sub. This will be for 95% home theater use and 5% for music. I currently have a Denon avr788 receiver. Here are my questions:

Will the avr788 be enough to power the new Axiom speakers?
With that size of a room/viewing area will the vp100 be fine or would I need to goto the vp150?
For fronts what should I go with m22, m50, or m60?
for the rears what would be best for mainly home theater one of the bookshelves or the qs4 or qs8?

I can probably spend a max of about $1300. Anything else would probably be at least 3-5 years before I would be able to purchase anything else.

Option 1 get the m60 & vp100 use my old bookshelf speakers for rears? My old bookshelves are 20 year old american acoustics with 8" woofers.

Option 2 get the m60 and vp150 use my old bookshelf speakers for rears?
Option 3 get the m50's, vp100 or vp150, and qs4?
Option 4 same as 3 but go with the m22's instead of qs4's?
Option 5 you pick.

Thanks
