I've got 2 small bose speakers.. they're the ones that are directional, the tweeter section and the midrange can be turned.. I don't know what the model number is....

Anyway would those work for the back surrounds? Well.. I know they'll "work" but will they sound good? Should I go for something that is more full range? I need something that is unobtrusive to hang from the ceiling..

I may just try them for a little while.. If they are really bad I think I may make my own speaker using the Fostex full range drivers (4" or so)...
