I want to avoid running speaker wires through the wall (double insulated/ with double cross bracing). I have onkyo bookshelf rear speakers (3) wich I have screwed keyhole hanging brackets on. I purchased 3 ceiling mounts. Can I just run the speaker wires for the rears from the receiver in the front of the room ,under the baseboards to a closet near the receiver , up the wall (not in the wall) through the ceiling and then across the attic floor and down through the ceiling to the speakers? Then I would not need to run anything through the wall. If so would you just drill a hole and fish the wire through or is there a better way? Also , do you feel sheet rock anchors would hold the ceiling mounts and speakers or would you take the time to place 2x4 studs between the joists? Also, how could I mount the center speaker from the ceiling? My seating area is directly below the center speaker so it almost needs to face down....an obvious problem with a keyhole bracket at the top? Thanks for any advice you can offer a me.
