What Polk soundbar can be connected to my AV receiver?

I haven't upgraded my equipment for about 17 years, and now we want a little better, crisper sound in our living room.

I want to run a really good soundbar connected and controlled by my AV receiver to my Sony TV supporting an ARC and optical hook-up. I use my receiver to control all my other media players (Blu-Ray, cd player, tape recorder, etc.
I am using a 10" woofer, and ceiling mounted 8" speakers which I still want to use.

It seems that all the new soundbars are powered, and incompatible with a receiver.
Although a nice virtual surround sound would be good, my space limitations don't allow for a full Dolby Atmos environment. I would guess that it has to be a passive soundbar.

What Polk soundbar would be recommended for a small living room, yet providing full sound? I would appreciate any suggestions.
