Meet Sunfire's purpose-built, 2.4Ghz wireless kit that is specifically designed and tuned for subwoofer applications. Simply connect the transmitter module to you're A/V processor and the receiver to your subwoofer. All you need is a power outlet near the sub and you're ready for plug-and-play bass with the freedom to move the subwoofer to any location in the room. And for improved performance, connect up to 2 receivers and subs from a single transmitter for flatter frequency response and higher output. Get more bass from any space - only with Sunfire DS.
