What I have learned about home audio: Setting up a HT in a common area is a whole bunch of compromises.

Due to access issues with a cabinet, I needed to relocate my left and right mains.

I did a little re-arranging, and now have the speakers sitting on shelves in my entertainment center.

The good news is that the tweeters of my front soundstage now line up fairly well, and I can set my M3's upright for optimal horizontal dispersion. I can also toe-in the speakers for improved on-axis listening, and the added height helps to fill the larger area with sound as opposed to being blocked by furniture in the room.

HOWEVER, the shelves are only 10 inches deep, and NOT open at the back. As a result, there is not much clearance for the port at the rear of the M3.

I have the fronts crossed over at 80hz.


Would any of the Axiom Gurus here please help me out with the following?:
1) Is port clearance an issue considering my crossover point?
2) Any tips on taming the resonance of the bookshelves?

Thanks!
