I have the Boston Acoustic Center Channel HS225 Midnight. It has two screw in keyhole spots that are about 6" apart. Is there any type of center channel mount that will let me swivel left and right? The wall my tv and center channel is mounted is off centered so I need my center to be able to turn a little right. I would rather not just put an invisible shelf up there and turn the speaker on the shelf. I tried searching the forums and apologize in advance if I missed it on another post. Thank you from a newb!

something like this may work http://www.monoprice.com/products/product.asp?c_id=108&cp_id=10828&cs_id=1082804&p_id=5558&seq=1&format=2

try to find a mount rated for 2x or 3x the weight of your center channel (BA shows it at 11 lbs). You would have to attach it directly to the speaker enclosure (very carefully), since the hanger slots would be useless with this type of mount.

another thought is...you might consider one of the smaller TV swivel arm mounts that would allow you to position the larger center channel speaker along with the TV. They could allow the easy positioning and easily support the weight.
