Hello,

I currently own the Motion 40s from Martin Logan and was curious if anyone has compared these two speakers before or could give some insight on which would have better SQ./performance.

I currently am able to return the Motion 40s and grab the Sierra Towers.

The listening room is a small 12x12x8, not perfectly square. My receiver is a Denon X4100 and UM-18 (DIY) subs. There are currently 5 acoustic panels, but I have several more I haven't put up yet. Still making lots of changes.

I would say I listen to both music and movies pretty equally. I'm not that critical of a music listener, but appreciate great sound. I just like to listen to music, not critic it. All channels are crossed at 80hz, except the front heights, which are 120hz. I don't currently have rear surrounds installed, but I ordered a pair of bookshelves to test them out. So that means I have a 7.2 system, with only one pair of surrounds.

If anyone has any questions, feel free to ask.
