2 Center Speakers in M-C/HT System?

I have soliloquy sat-5's all around with a velodyne ULD15 II for a sub. I could not fit the soliloquy center channel where I needed it and went with a pair of sat-5's instead. I laid the sat-5's on their sides about 6 inches apart with the bottoms together. I also made sure that the amps for both are itentical as well as the cabling to avoid any cancellation. The system sounds great! It also fills the center better since I have a 6 foot front projection tv and the R/L speakers are about 16 feet apart.

By the way, Soliloquys are upside-down designs. My tweeters are on the bottom. I have the bottoms together. Make sure that you don't toe the speakers in. I would have them facing straight out.
I had to use 2 instead of a center because there is a support beam right up the middle of the wall.
My system:
Anthem AVM-2
HK Signature 2.1
Soliloquy sat-5's (6 of them)
Velodyne ULD15 II
