Oz,

I have the M80s in a similar size room as yours but the ceiling height is only 7.5'.My 80s are 18" from the back wall 2.5' from the side walls and toed in just slightly.I Listen to classic rock,blues and a little jazz here and there,and imo the 80s sound just great in this setup.

I do believe you will be pleasently suprised just how much bass you get from them.You could defintly get by without a sub,for music only.Even though they have a high sensitivty rating they really do like the power put to them.I too run them with a Rotel RB 1080 @ 300 watts @ 4 ohm.Looking at how you will have them set up I see no problems with placement.
