I'm looking for small (probably better passive) speakers for a multi-channel (16 channels twice) audio installation. I intend to mount them on a wall. Any suggestions?
You can buy naked speakers from a lot of different electronics supply companies. It might be a good way to go for you, because they'll be very cheap. The down-side is that they won't have any kind of housing to speak of, and you may have to do some soldering (or at least get some clip leads) to cable them up.
As an example, here's what www.allelectronics.com offers: http://www.allelectronics.com/make-a-store/category/580/Speakers/1.html
I've ordered from this company before, and have been happy with their service. There are plenty of other places you can order from though.
Hi I have used and very much like the speakers from a company called Audica. They are a UK based company and the communication I have had with them has been extremely helpful. The website address is www.audicapro.co.uk
I have seen their products used in churches, stores, restaurants etc and I've been impressed whenever I see / hear them.
Hope this helps.
