Hi I recently started upgrading my HT setup with axiom products. I own an Onkyo 803 7.1 reciever, a pair of axiom m22's for the fronts and a svs subwoofer.

First off, I was deciding between the different center and surrounds. If I can afford the 150 should I purchase it over the 100? I figure these speakers are all matched? Or would the 150 be overkill on the m22s?

With the surrounds, I`m probaly going to pick up 3 of them. I'd like to go with qs4's for the price is this a big downgrade compared to the qs8's.

Finally I`m wondering what the best spots for the fronts and surrounds to be placed? I'll add I will probaly pick up the stands made for the m22's.
The center is going to be under the tv on an a/v rack, roughly sitting hieght. The fronts will be on the stands, how far apart should they be from the TV? I`m guessing they should be the same distance from listening posistion af the center channel, but should be toed in slightly?
Finally what do you do with the surrounds? I was thinking of hanging them from the walls, back left, back center and back right. should they be up high aimed down towards the listening posistion?

Sorry righting this after work in the morning on a pot of coffee Minds a little scattered.
Forgot room size....
Right now its a split room, half kitchen/ half living room. The living room area is 16'(length) x 12' (width). The setup is against one of the shorter walls and the couch/chair is is in the middle ofthe room 8' away.

This is an apartment and I plan on moving in a few months so generic info would also be appreciated.

Allright well thanks for putting up with my ramblings.
