Why Choose a Wireless Sub?
A subwoofer is a dedicated bass speaker designed to handle the low frequency effects in audio systems. The “.1” in a 2.1, 5.1 or higher surround sound system, the subwoofer plays a critical role in transforming ordinary sound into a spine-tingling experience, especially on action and adventure films. Because subwoofers handle such low frequencies, you’ll often feel the bass as much as you hear it.
Where you place the subwoofer will depend on your room’s acoustics and your own personal taste but placement flexibility is key. Sometimes, the best sound is experienced when the subwoofer is located in a corner, away from the TV and receiver, but this means running cable in the wall, underneath the floor or along the base boards—not always an easy task. OSD Audio’s NERO-WSA bypasses this step so you can place your sub anywhere near a power outlet.
How Far Is the Range of the NERO-WSA Wireless Subwoofer Kit?
Our NERO-WSA has a line-of-site range of 150 ft., although each environment varies and metal objects and obstacles can affect transmission. The 5.8 GHz frequency works best at line of sight, but you can hide the subwoofer transmitter/receiver in another room or behind a sofa; however, transmission range may drop. Reliable and Backed with a 2-year Warranty Compatible with most receivers, amplifiers and powered subwoofers with RCA inputs/outputs, the Nero-WSA wireless sub is backed with a limited 2-year warranty and a 30-day satisfaction guarantee.

“I received the pre-amplifier, but it did not function properly. I obtained an return authorization and shipping label. I was told it would be repaired or replaced. I am waiting for a response.”
