Get more bass from any space! Bass is meant to be felt and drive the audio experience to new levels. Where you place a subwoofer has a huge impact on sound quality, but sometimes you can’t get a cable to the optimal subwoofer location. With the SpeakerCraft SC-WIR-RX-US Wireless Subwoofer Kit, you can place the sub in a location that achieves the best possible sound for the room. Simply connect the transmitter at your A/V source and the receiver to your subwoofer’s USB port and you’re ready for plug-and-play bass. All you need is a power source for the sub and you unlock the freedom to strategically place the subwoofer in its optimal location. The basic kit includes 1 receiver and 1 transmitter, with the transmitter supporting up to 4 receivers for use with multiple subwoofers. Additional receivers are sold separately.
