  • $ 199

The WTX Wireless Transmitter is sold separately in all cases. For existing models, such as S.0, S.5, and S.9, the WRX Wireless Receiver is also available separately, and can be connected to the subwoofer input to achieve full wireless connectivity. The largest S Series model, S.10, possesses the WRX Wireless Receiver already built in.

The Sumiko WRX Wireless Receiver provides the same connectivity as the traditional wired setup. Speaker level and LFE connections can be sent over the air to the subwoofer simultaneously, creating the greatest flexibility in placement.
