I rescued a pair of KEF coaxial driver/crossover setups from the trash pile. They came out of a pair of Ci200QT motorized in-ceiling speakers. 8" woofer with a 1" coaxial tweeter, 6 ohm impedance, 88db sensitivity, xover at 2.5kHz (seems high for an 8" driver?)
I want to throw them in a box and see if they are good enough to use or give to a friend. I'm really not sure what kind of volume I should be putting them in though. They are designed for in-ceiling applications, where they would typically be in air spaces ranging from 1-2 feet^3 to fully IB. They originally had a back box that swung them down from the ceiling, but it had a large (1"x 7") vent directly to the back space, with a very fine mesh screen over it. It didn't seem to be aperiodic though, unless it only provided a very low amount of resistance. I think it ensured they were IB or close to it.
I'm not expecting super hifi here, just usable sound. Two speakers plus an old beater 2ch receiver makes a nice ipod bookshelf system for friends that want to add sound to rooms, and I like to do that for them.
I'm inclined to think I'll need a big volume, but I really don't know where to start. I assume sealed for simplicity, as I don't know any specs for these speakers for winisd or anything.
Any suggestions?
