Looking for input on Legacy Audio speakers purchase.

I don't want a bookshelf speaker. This will be my last speaker. Just concerned Aeris is too big for 15x21 room. Another reason considering Focus SE because I don't think is too big for 15x21. 

Meant to say in bybass mode for surround not music

I was thinking that the McIntosh MC611's would be overkill for the Aeris with built in amplification.

 I have heard the Aeris with the wavelet with McIntosh 1.2KW mono blocks.

To stereo5,
Did the Aeris with wavelet and Mac amps you listened to at Audio Classics have the built in bass amps?. I Know they have sold custom Aeris with no wavelet and no amps built in at Audio Classics.

Thanks All!

My room is 15x21. Too small for Aeris?

Thanks again to anyone who gives input!

Problem is can't demo the Focus SE or Aeris in my room (local dealer said no). The reason I bring up the size of my room (15x21) is because I had Martin Logan Summits that worked great in my room. I then went with the CLX and in a minute I realized that they needed a larger room to breathe. Since the Aeris is a different design implementing an open baffle I would think they need a larger room than the Focus SE to breathe.
Anyway, the reason I started this post is to get peoples thoughts on using my McIntosh MC611 amps with Focus Se and McIntosh C2700 preamp vs. Aeris with Wavelet preamp. The size of my room should also be a consideration for anyone's thoughts on the 2 setups I'm considering which I originally forgot to mention in my post.
