Now you can have more placement options than ever using the optional PWSK-1 wireless kit fo DSWPROwi subwoofers. The wireless system is made up of a small wireless dongle that connects to the subwoofer's amplifier plate. No additional AC power connection is necessary, because the dongle connects to the amplifier's power supply. A compact wireless transmitter connects to an A/V receiver and sends bass signals to the subwoofer. There's no latency, no compression, just big bass for your viewing and listening pleasure.
