Sound bar with surround speaker that doesn't require power?

I currently have a VIZIO M512a which included surround sound rear speakers. My house came pre wired for 5.1 surround sound on the ceiling so I mounted the 2 rear speakers on top and then connected them via speaker wire to RCA cable. No separate power connection needed. I like the setup as it keeps it clean.

Anyways the sound bar left drivers are starting to fail as I hear rattling at higher volumes and looking to upgrade.

I'm looking at the Samsung Q990F which includes wireless surround speakers but require them to be powered via power cord. Unfortunately there is no power outlet in the ceiling so a direct replacement for my current setup would not work with these.

Are there any nicer premium sound bars with surround speakers that doesn't require them being powered via a standard power cord?
