Very similar question like Is it a good idea to stream a vinyl turntable via Bluetooth? but with a wireless connected Subwoofer.
I soon own a HT-G700 3.1ch Dolby Atmos® / DTS:X® Soundbar sound system, the connection to Subwoofer is wireless.
Wireless subwoofer delivers powerful bass sound
I assume the same answers apply? The question is identical, or is it?
