ok, here's my setup

room 14'(W) x 18'(L) x 10'(H)
Front : M60v2, VP150v2
Side/Rear : Mordaunt Short Avant 903i x 4
Sub : SVS PC12 Plus

I have the Mordaunt Short Avant 906i (floorstander) and the MS 309i subwoofer in the living room. Since we seldom switch on the surround system in the living room, I am thinking of moving the 906i to HT room as front wide and the 309i as a 2nd sub-woofer.

I would be losing the rear surround if I opt for the front wide as my Onkyo NR808 can only support 7 channels.

My questions:-

WOuld I appreciates the front wide sound vs rear surround sound?
How would the 2nd sub improve my LFE since the output of the 309i is day and night vs the SVS?
Would the MS sosound good with the Axiom?
