Ok, apparently there is an installation kit for these from Klipsch.
I've searched and I can't find any dealers that actually have them in stock.
Anybody have any suggestions on who I can get to order me a set to mount my pair in my ceiling? I don't know whether 1 or 2 come in the box. I need whatever it takes to mount 2 speakers in my ceiling.
I need the IK-502-C installation kit. Here's what it looks like.
And here is one from a different model but shows it from a better angle.
