With the Sony SA-Z9R, you can create surround sound in your living room. These wireless rear speakers are to be used in combination with the Sony HT-ZF9 soundbar. Connect the devices via Bluetooth. With 50 watts of power, the speakers expand the sound of the soundbar for a complete surround sound. The sound contains low base tones, thanks to the built-in subwoofer. The cutout on the back of the speakers allows you to easily hang them.
