The NERO WRSKII5.8 GHz Wireless Rear Speaker Kit with Sub Out lets you enjoy all the acoustic benefits of a 5.1 surround sound system without the hassle or lack of access to running speaker wire from your home theater receiver to the rear surround speakers. This compact wireless surround sound kit includes a transmitter/receiver that sends the audio signal using the faster and more reliable 5.8 GHz frequency from your amplifier/receiver to the rear surround 2-channel amplifier where the surround speakers connect using the speaker wire supplied with the kit. The kit also includes an input/output to connect a powered subwoofer so you can enjoy the rumbling bass that makes movies and music even more enjoyable. Start binging your favorite shows or play your digital music library with heart-pounding surround sound without having to tack speaker cable around doors and along floorboards or snake cables through the walls or crawlspaces.
