We're looking to use a few Sonos ZP120 units in our new home and would like to match them with good, if not necessarily high-end, in-ceiling speakers. Each person with whom I have spoken has had a different recommendation (e.g., Polk MC60, SpeakerCraft AIM5 Three, B&W ccm618, and Klipsch cdt-2650-c). I have been unable to find any useful reviews of any of these speakers (perhaps because they are at the low end of the range), but I would like to get the best we can out of our limited budget (up to $250 per speaker). Any suggestions for in-ceiling speakers--especially if it is choosing one of the mentioned models over the others--would be sincerely appreciated.
