I realize the acoustech tower speakers aren't the quality of the axiom products. However, I'm just not sure if if they would sound that much better to justify the upgrade. My main concern is the the size of my room 14'w 20'l with a 13' cathedral ceiling with the room open to a foyer,stairway and dining area. Listening area is around 12 ft. from the mains. The reason I initially went with the bic's is due to space constraints. I can't go too deep. Hence, the 22's not the 60. I have an outlaw 1070, axiom center and outlaw lfm2. Listen to music 80% and seldom very loud. Any thoughts?

Well for starters, it is very important that your left/right speakers match the center speaker. It is not a good idea to mix/match different brands, especially across the front 3 speakers. You want them to be tone/timber matched.
