Maggie Home Theater Speaker Set-up advise

Hi-
I'm using pairs of Maggie 1c's and 2c's for my four surround channels in a 7.3 setup. I currently have them set up as follows: the side surround pair are to the right and left of the main listening area, pointed to the rear, parallel to the front and back walls, so that when looking at them one only sees the one inch side pannel. The rear surrounds are parallel to the side walls, directed toward each other, located directly behind the main listening area.

Obvious options to this setup include pointing all or some speakers at the listener, and having the rear surrounds point toward the side walls they are closest to.

The listening room is roughly 19 feet wide and 18 feet long with a 8 ft ceiling. I'm using Outlaw's brand new processor and 7 channel amp.

With this setup, all speakers have at least 4 ft in front and in back clear. The side surrounds are less than four feet from the walls, but since their front and rear are unencumbered, this seems to be an acceptable compromise. My wife gets along quite well with Maggie--she says as long as I'm a good father and don't chase women or do drugs, she can handle having Maggie in her living room.

Finally--I know Magnepan makes a dedicated center speaker, but I'm also thinking of suspending a Maggie horizontally above the T.V. four feet from the back wall. Other than engineering particulars, I'm wondering if this adversely affects Maggie, and if so, how.

All comments and advise welcome!

Thanks,
Bruce
