R-5502-Ws as rear in condo, what to match with?

[Briik]

This is actually a bit more complex than the title suggests.

Long story short: I've installed R-5502-W speakers in my rear wall as part of my 7.1 system. That wall lies in the middle of my condo so I'm not concerned about transferring noise to my neighbors, however the front of my HT will be on/in a wall that I share with my neighbors. I do not want to raise the possibility of them being disturbed by my audio. So, can I consider any in-wall speakers that would, perhaps, fit in a custom-made housing to keep the sound from penetrating backwards into the wall? Is there another way to do it so that I can still use in-wall speakers? If not, which Klipsch speakers would you recommend to match with my R-5502s? I'm new to the HT world and not looking to spend over $900 for a pair and I can't find another Klipsch speaker that's recommended for a 130w amp - I'm using the Onkyo HT-RC160 AV receiver/amp.

Also, I've got maybe 2 inches of room behind my drywall where the surround/side speakers are, when I replace them is there a recessed speaker that could fit with only 2" of clearance?

Thanks a lot in advance!

I see that nobody has read this posting yet. Am I in the wrong section of the forum?

Room is 22'L 20'W 20'H on left with a drywall ceiling cutting to 18' on the right side (50/50 split). Hardwood floors, drywall all around, with open L/R 'walls' (windows/kitchen).

My surrounds are at 8' height, my fronts and sitting position at 4'. At this point just looking for recommended speakers to match R-5502Ws with 130w rating and in-wall speakers that take less than 2" of clearance behind the drywall. Thx.

I would go with an early 90s Shiraz, don't cheap out either.
