Alright, I'm stuck...

My room is roughly 25ft long. 15ft wide.
Fronts are 18" off front wall. Theater Seating is 9' away from TV. And rear's are against the back wall. So from front speakers, to rears speakers, you are looking at about 22 ft. Give or take. Would it be worth throwing in a set of Di-Poles on the sides to "fill" the room/void between the front and the rears?

It's either keep my Bi-Amp setup and 5.2 or Lose the Bi-Amp and go 7.2

What'a think?

You should definately go 7.2. If you can get speakers behind your seating I would almost always got for the 7.1/2. If your seating is pushed against the far wall then its 5.1/2 land.

I would add a pair of speakers directly to the sides of the main seating position. Bipoles, dipoles or monopoles; choose based on preference. Having 4 surround speakers will give you greater wrap-around envelopment and stable side vs rear directionality in the surround field.

Okay, then my next question is, should I stick with KEF? IQ8DS's? Or should try the Axiom QS4?

looking at your distance marks, a false wall at 1 foot front a 4-6 foot space at the back, a mini room to store av gear into

with this type of distance to you might want to talk the people who fit out commercial theaters and cineplexes

i doubt you will find a domestic install outfit that covers that distance either in width or in length...

I should have my Axiom QS4's this week, along with The Fast and The Furious trilogy to test the new 7.2 setup on.
I will fill you all in...
