A: undefined
Q: Would this speaker be compatible (combine) with a Klipsch powered Bluetooth sub woofer? Thanks
A: The RP-504C II is a passive, non-powered speaker that will need to be connected, via speaker wire, to a receiver/amplifier for power and audio reproduction. Depending on the model of receiver/amplifier, a BT subwoofer could be connected to achieve a 1speaker/1subwoofer setup.

Absolutely love this thing. It’s a beast. Sounds amazing and looks great. Definitely improved my home theater experience. Dialogue has never been more distinguishable and clear. I’ve considered a 3 channel amp to boost my FOH but it does fine on my Marantz SR6013. Upgraded from a DCM center speaker. Scaling is more more appealing too under my 85” Sony.

This Klipsch RP-504c is a monster. I didn't realize how massive this thing is. Sounds great! Would absolutely buy again.

Just buy the center. After trying other Klipsch centers. Beak in time needed, but sounds great. Not my dream speaker system of years past. For price point $ value there.
