ATC SCM7 vs. Proac Studio 110

I have the power to drive the ATC's. Your summary is excellent, I think, based upon reviews that I have read of each.

I'm leaning towards the ATC for the reasons that you describe as well as it being a sealed design and better suited to rear-wall installation.

I'm going to mount them on brackets attatched to a wall.

with the power, the atc

Yeah ATCs will be the best choice if you intend to mount them to the wall. Bass seems to get reinforced without blurring the image. By theory the ATCs should have better bass extension than the Proacs but not in terms of power where a ported bass alignment should give. So with the close wall positioning, the bottom octave of the ATCs will fill in quite nicely without boominess.

I agree - the roll off on a sealed box is less steep - so ultimately you can get some useful deep bass compared to the risk of "one-note" bass that sometimes comes with small efficient ported designs.

They won't be mounted directly to the wall, just to clarify.

They'll be on Target (the UK company) brackets which bolt to the wall and then you set your speakers on them. I have them installed now with Matrix 805's and the backs of the speakers are probably 5"-6" away from the rear wall.

I definitely think that the 805's are too large to be mounted that close to a wall, but the one with the good tweeter sounds good located that way.
