i have a 60 inch lg plasma over my fireplace. it is connected via hdmi through an access tube that goes from above the fireplace to a built in shelving system next to the fireplace. the tube unfortunately isnt very wide and given the poorly placed angles of the tube i had a hard time getting my hdmi cable and an optical cable through the tube. Thus i dont think i can get many more cables through the tube. id like to improve the sound primarily for watching tv and movies. are there any wireless speakers that are worth looking at to get surround or simulated surround or possibly 5.1 like sound. a photo of the room is attached for any ideas or recommendations.
