Since a bathroom has less than ideal acoustics to start with, I installed some inexpensive Monoprice 6.5" ceiling speakers about 1 year ago. I was very pleasantly surprised at how good they sound--no regrets, no intent to "upgrade".

For installation, a RotoZip with the circle attachment was the heat at cutting out a perfect circle with smooth edges!
