TCL TS8212-SW Dolby Atmos Bluetooth Wireless Subwoofer is like new except AC power cord lost in the move. To connect a TCL wireless subwoofer, TCL Electronics recommends:
• Ensure both devices are powered on, then attempt automatic pairing by keeping them close and allowing them to connect automatically
• If auto-pairing fails, manually press the "Pair" button on the back of the subwoofer until the LED blinks
• Then press the "Pair" or "Subwoofer" button on the soundbar's remote or main unit
• Solid amber light on the subwoofer indicates a successful connection
It is about 7-1/2” sq. x 14” H, mounted on vibration-reducing rubber feet. Comparable used TCL Woofer retails on-line in the $40-range, typically out-of-state, with a postage burden of about $20, bringing cost into the $60-range. A local bargain here, available for pick-up in San Rafael, cash, Venmo, or PayPal.
