Product Description & Reviews

How Does the OSD Audio WRSK250 2.4GHz Wireless Speaker and Subwoofer Kit Work?

The WRSK250’s transmitter connects to your home theater amp/receiver with RCA cables and plugs into a standard electrical outlet.

The WRSK250’s receiver connects to the surround speakers via speaker cables (included) and to the powered subwoofer via RCA subwoofer cable (not included) and also plugs into a standard electrical outlet. The transmitter then sends the audio signal to the receiver over the air via the 2.4GHz frequency, the same reliable frequency used by cordless phones, routers and other wireless devices.

Because most households have several other devices operating on the 2.4GHz frequency, the WRSK250 includes 34-selectable channels so you can dial in the most reliable and steady signal. While the 2.4GHz frequency works best line of sight, it’s not critical so you can hide the receiver/transmitter behind a sofa, inside a cabinet or even in another room. Keep in mind that while this is a wireless solution for transmitting an audio signal from a home theater system’s receiver/amp to the rear speakers and powered sub you still need to connect the speakers to the WRSK250 receiver via speaker cable.

Reliable and Backed with a 2-year Warranty

Compatible with most receivers, amplifiers and powered subwoofers with RCA inputs/outputs, the WRSK250 2.4GHz Wireless Speaker and Subwoofer Kit gives you more flexibility when designing your home theater system and relieves the stress over how to bury or hide the speaker cables. We invested a lot of time into the sound quality and integrity of our wireless rear speaker and subwoofer kit to ensure the device transmits a reliable signal with minimal latency or drops, and we back this kit with a 2-year warranty and a 30-day satisfaction guarantee.
