Proper way of mounting mid-sized speakers to wall/ceiling
I'm moving into a new house, and would like to "cleanly" install my 5.1 setup, meaning, my TV will be mounted right on the wall, no wires visible, the front speakers mounted on the wall to the left and right of the TV.. center channel underneath.. no wires. I'm just not sure how to go about doing this. I assume there must be kits out there that let you "hang" a heavier speaker off the wall, while leaving some clearance for wires? Should I use a wallplate and run a short piece of wire between the speaker and the wallplate? Or just route the wire through the wall, and make the hole look pretty?
The backs of my speakers don't have holes for hanging them/etc as far as I know. At least the Sony's don't.
I'm still debating how to do my rear speakers -- the wife does not want stands, so ceiling-mount it is. They are somewhat large/heavy as well.
My speakers (and their weights):
Fronts: Sony SS-MB150H (7.7 pounds each)
Center: Sony SS-CN550H (12.5 pounds)
Rears: Polk Audio T15 (8.5 pounds each)
Thanks in advance for any advice.
