Can anyone recommend some inexpensive in-ceiling speakers to be used for background music in a basement? I am hoping to use a single stereo input speaker in 3 small rooms and a pair in another room. What size of room can a single stereo input speaker handle? The seperate room is 10x13, and the rest is an big L-shaped room with a bar on one end. The long part of the L is 24 feet long with a big 8 ft soffet in the middle, so one speaker to the left of the soffet and one to the right, and one speaker in the bar area. Also, when I wire in for the single stereo input speakers, I assume I have to use speaker wire with four wires. Having never used single stereo input speakers, I am not sure. Thanks.
