Hi Ninsaga,
I have recessed ceiling speakers in my house, and given the choice, I would not do it again. I would for either small corner speakers, wallmount speakers, or plain bookshelf speakers. Sound quality on ceiling mounts is poorer, and also beleive me, after a few years, the "coolness" factor will have worn off, and you'll be stuck with them for another 30,40 years unless you replaster.
