I had installed 8 sets of ceiling speakers installed by the builder in my new condo. I used Cambridge Soundworks speakers for all of my speakers. Until recently they had retail stores in New England and California but they are now mostly web based. They have a wide range of speakers and prices so I was able to get higher end units for the living room and saved money with smaller/cheaper units in the master bath etc. Also purchased their outdoor units for my deck and have some book shelf speakers for the bedroom. The clarity is great. I have the whole house wired into a two zone system but had to get another amp to power it all up. When I have the whole house filled with music such as at a party the sound is amazing. The ceiling speakers in the living room are also tied into the 5.1 surround sound for music and also used for TV sound. (I went a bit crazy doing the whole house but it sounds great). Look at them at www.cambridgesoundworks.com . They frequently have sales so signing up for their e-mail newsletter may save you some money.

Hi,

I am a bit too late here probably, but I am running 24 cieling speakers from PSB, through a Matrix amplifier 8 zone system throughout my home and they sound pretty good. Although the amplifier is exspensive the PSBs are about $200 to 250cdn a piece.

My experience is that you will not get good imaging nor soundstaging through ceiling or wall speakers, if that is your aim.
A reputable speaker manufacturer and store outlet with a good return policy should give you what you are looking for.
