I am helping someone who is going to be bed-ridden for some time set up a high-quality 2-channel stereo system in their master bedroom. Originally the system had two mid-sized tower speakers in each corner of the room that faced the bed. But in order to maximize floor-space, these speakers are going to be used elsewhere and we want to install smaller, book-shelf sized speakers higher up near the ceiling. We originally tried in-ceiling speakers but the sound and directionality did not really work well. They didn't sound good enough (the owner listens to classical music and I would classify him as an audiophile). So instead, we would like to mount a very good set of bookshelf speakers on brackets but there are some limitations.

- The speakers cannot be taller that 12" (I suppose we could install the speakers sideways, but I am not certain how that would affect the sound).
- The speakers cannot be too heavy or too deep in size
- We want a speaker that can play well in the lower frequencies
- I want to stay clear of anything that will require a sub.
- The room is about 18 x 18' and has a few odd corners, but not that will affect the line of sight to the speakers.
- I have already installed 14 gauge speaker wire in the wall and terminated the ends where the speakers will be installed.

Thank you for your help.
