my current setup

I kept talking about it, here it is.

VSX-1018
Optoma hd65 & 120" display surface (wall)
2xM22ti
2xQS8
1xVP100

1x 12" psb sub

my room is around 14x14 (dimensions are changing every day!!!) one day I will remember the correct measure! :-)


Quick recap:
I'm wondering if M80 would be worth their price in my setup. The wife needs to find the upgrade worth the money.
