I did the PRO-180RPC LCR's for top front and top rear, and regular PRO-180RPC's for top middle.

Any interest in a brand new, unopened pair of Klipsch AW-650's? We bought four pairs last month from authorized dealer for an outdoor project, but ended up only needing three pairs. Again, the box hasn't even been opened. Let's go with $450.

504C is better.

Has anyone installed Klipsch PRO-180RPC LCR's with the SecureFit system into double drywall? I'm wondering if double 5/8" drywall on my ceiling would be problematic for it or not...

Well, that depends on room setup. In general, yes, monopole is ideal for Atmos. But in close quarters, especially for side surrounds, bipoles such as RP-502S may be better. I have a very narrow room and have RP-8000F's surrounding me, except for the side surrounds.
