OSD Audio’s WSK-100 2.4G Wireless Subwoofer Transmitter and Receiver Kit allows you to add a powered subwoofer to a new or existing surround sound system without the hassle of having to run cable from the receiver or amp to the sub.

What Is a Subwoofer and Why Choose Wireless?

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 (typically between 20–200 Hz), 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. If this is not something you relish doing, OSD Audio’s WSK-100 2.4G Wireless Subwoofer Transmitter and Receiver Kit could be the ideal solution.

How Does the OSD Audio WSK-100 2.4G Wireless Subwoofer Kit Work?

The WSK-100 allows you to locate the sub anywhere there’s an electrical outlet, allowing for much more placement flexibility. Here’s how it works. The kit includes a transmitter and a receiver as well as the necessary cables and power adapters. The transmitter connects to your amp or receiver's subwoofer RCA output, then sends a wireless signal over to the kit’s receiver which is connected to your powered subwoofer's RCA input. When the transmitter and receiver are within 100ft of each other, the low frequency sound is transmitted to the subwoofer via the 2.4GHz broadcast frequency, the same reliable frequency used by cordless phones, routers and other wireless devices. Because most households have a number of other devices operating on the 2.4GHz frequency, the WSK-100 includes 34-selectable channels so you can dial in on the most reliable and steady signal. While the 2.4GHz frequency works best at line of sight, it’s not a deal breaker so you can hide the subwoofer transmitter/receiver in another room or behind a sofa.

Reliable and Backed with a 2-year Warranty

Compatible with most receivers, amplifiers and powered subwoofers with RCA inputs/outputs, the WSK-100 gives you more flexibility to place a sub in the absolute sweet spot so you can enjoy the best sounding bass your subwoofer can provide. We love what quality bass brings to the home theater experience and invested a lot of time into the sound quality and integrity of our wireless subwoofer kit to ensure the device transmits a reliable signal without latency or drops. We back this wireless subwoofer kit with a 2-year warranty and a 30-day satisfaction guarantee.


How the Wireless Subwoofer kit Works

Place the transmitter and receiver within 100ft each other, on a flat surface or mounted on a wall.
1. With the audio source off, connect the transmitter to the subwoofer jack with the RCA cable.
2. Connect the supplied AC adapter (9V, 200mA) to the transmitter DC IN 9V jack, and then plug it into a standard household outlet.
3. Connect the receiver to your subwoofer with the RCA cable.
4. Connect the supplied AC adapter (9V, 200 mA) to the receiver DC In 9V jack, and then plug it into a standard household outlet.

When you connect the power and signal cable, the transmitter and the receiver LED's light green. If there's active audio source, the receiver automatically activate and send the signal to subwoofer input.

If you experience any interference, press and hold the "M" button on both transmitter and receiver units, both units will automatically change the channel and link.

Note: The wireless subwoofer kit will enter into standby mode 17 minutes after there's no signal.

Work Great
November 26, 2016
I was having problems with a setup that Best Buy Geek Squad did. Cost me $99.00 and did work well at all. Kept turning off and I had to keep turning them on each time I turned on my system. Now everything works great, in fact it's awesome.
Great working and paired easily.
Best Uses:
Wireless for sub woofer.

A very well built kits for reliable operation

Saw this new kits from OSD and install for my customers over the weekend. It works out great because otherwise I have to run the wire from closet to the room. It was about 30ft from receiver to the subwoofer and the signal travel through a wall. Didn't find any delay and the pairing was easy. The kit comes with transmitter and receiver while other factories charge them separately, great value!
Comes with transmitter and receiver as a kit pairing is easy no need to run the wire
