Produce Realistic Bass via Wireless Connection

Perfect for home theaters with crowded space and/or limited wiring options, the small, square-shaped Air-Bus Wireless 8 In. Down-Firing Subwoofer (110W), measures only 13 inches each way and features a built-in wireless audio receiver that eliminates the need for a hardwired connection to the rest of your A/V system. Simply pair the subwoofer with the optional wireless audio transmitter (AB-Tx, sold separately) to send bass audio to the subwoofer without any wiring. The subwoofer can always be wired if the situation changes.

  • Compact design fits inconspicuously in small spaces
  • Built-in lossless audio receiver allows wireless connection
  • Can be hardwired using a standard RCA cable
  • Laboratory-tuned for true deep-bass performance
  • Includes adjustable rubber feet for proper acoustic isolation

The Air-Bus Wireless Subwoofer features patented amplifier technology, accompanied by meticulous driver and system design. Finished with a non-reflective matte black polyvinyl, the subwoofer also eliminate reflections. Overall, the subwoofer delivers high-performance true, deep bass to your home theater system.

How to Enable Wireless Operation

Pair the Air-Bus Wireless Subwoofer with the Air-Bus Wireless Transmitter (AB-Tx, sold separately) to wirelessly transmit bass audio from your A/V system to the receiver. The transmitter has dual RCA inputs that accept left, right, and LFE signals (in right RCA) from virtually any A/V system.

  1. Optional wireless transmitter not included. Purchase the transmitter, model AB-Tx, to enable wireless functionality. Without the transmitter, a hardwired connection is required using an RCA cable, also sold separately.
  2. Only one receiver/subwoofer can be paired to a transmitter. If two receiver/subwoofers are used wirelessly, each device must have its own wireless transmitter.
