Interesting Mine came new with the screws in it . I just took 2 of them out and you can see some sort of threaded metal insert beyond the speaker back Maybe they changed design

I have a KV-3 that I would like to wall mount over my TV and was wondering if the 4 large screws on the back are for this purpose or are they holding something inside ? If the screws are for this purpose does anyone know of a bracket that will do the job ? I am using the Kv-3 with Chorus II's up front ,Boston Accustic Surrond Sat 6's for the rear with the Synergy 10" sub. I would like to replace the BA's with something Klipsch but don't which one to go with .
