What finish did you get the audiobytes in?
Possibly order up a finsih sample from Axiom the same finish as the audiobytes and use a portion of it as a wedge under the front of the speaker or just make your own shim and paint it as close to the same color as possible.
Fredk bent some acrylic plastic to make a custom center channel mount to put on top of his TV. I would bet you could do the same with some acrylic and be able to leave enough material on the back to act as a stop for the speaker to lean up against. I made a recipe card holder in grade 8 that would be about the right shape I have in mind, some thing along the lines of an exagerated/deformed 'S'. The bottom curl sets the angle and the middle gets flattend out and the top curl goes straight up.
