The WSK-SUB 5.8 GHz Wireless Subwoofer Transmitter and Receiver Kit lets you add heart-pounding bass to your entertainment system without having to run cable from the A/V receiver to the subwoofer. The kit’s transmitter connects to your AV receiver, then sends a wireless signal to the kit’s receiver, which is connected to a powered subwoofer or full frequency active speakers. When the transmitter and receiver are within 100 feet of each other, the low-frequency sound is transmitted to the subwoofer via the high-speed 5.8 GHz broadcast frequency. Add this to the 45-selectable channels, and your sound will be steady, clear, and reliable. The WSK-SUB allows you to locate your subwoofer anywhere there’s an electrical outlet so you can expand your audio system with rich, deep bass without having to tack subwoofer cable to floorboards or run it through the walls. The WSK-SUB 5.8 GHz Wireless Subwoofer Transmitter and Receiver Kit can be connected to a single powered subwoofer, a pair of powered/active full frequency speakers, or a small 2-channel amp with a pair of passive speakers.
