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.

Can I use with 1989 Carver 6250 Reciever with no preout or sub out. Only tape out, aux etc. I have out puts on equalizer also. My powered sub is Paradigm with RCA input. I hope my question is understandable thank you.
1 Answer
Hi Patterson:

You are correct; there does not appear to be a dedicated preamp or Sub output. And there are two Tape Monitors and a VCR tape out but only the VCR 2. So I think before you purchase the WSK100, you will want to see if either of the Tape Monitors are active. I believe the Tape Monitors on some Receivers needed to complete the loop of having both the Input (Play) and Output (REC) hooked up for them to work. I would try connecting the Paradigm directly to the Tape 1 output to see it is active no matter what source you have selected. See if the TAPE 1 output is playing music even if you do not select the Tape Monitor found on the front panel. If that does not work, then connect to Tape Monitor 2. If the Paradigm sub works, then you should be able to add a WSK100 connected to the TAPE Monitor that works. No reason to buy the wireless option if there is no output from the Tape loops of the CARVER.

Please let me know if it works;

Can I use it in my rear surround speakers in 5.1 home theatre 

Or anything else 

1 Answer
Hi Ritz:

The WSK 100 is a wireless solution for a Powered Subwoofer where you have a problem running a low-level signal cable (preamp) from your Audio Video Receiver to a dedicated location for your Powered Subwoofer. The WSK100 features a transmitter that connects to your Subwoofer output on your AVR. It broadcasts a wireless signal to the WSK100 Receiver which sits on top of your Powered Subwoofer. You typically need a dual AC outlet, one for the Powered Subwoofer and the second for the power supply for the WSK100 Receiver. Then you connect an RCA single mono sub cable. But you mentioned you wanted something to connect to your Surround Channel Speakers. That would be our WRSK250 which features a Wi-Fi Transmitter which connects to either the speaker (high) level outputs for channel 4 and 5 or links to the preamp (low) signal level. The Wi-Fi Receiver features a built-in 2x25 watt power amplifier for the Left and Right Surround Speakers. There is also a subwoofer connection between the transmitter and Receiver as well. The WRSK250 would be ideal based upon your application.

Because my receiver doesn’t have a (sub out) can I use the left or right channel out instead?
1 Answer
Hi Nolan: What receiver are you using? What preamp output are you planning to connect with from the receiver? It is usually ok to connect to one of the two sub outputs on an Audio/Video Receiver since that is true two-channel combined mono. But if you connect either a right or left output, it might limit your overall signal. The signal can be full range since the powered sub you are connecting to has the built-in crossover. If you can answer my questions, I should be able to better answer you; TL/5221

Will this work to transmit from a room indoors to receive say, on a patio outdoors? In other words, will the signal pass through walls? The distance from the room to the patio is about 50 feet, but there are two interior walls and one exterior wall in between. If it doesn't work, can I return it?
1 Answer
Hi Tony: Technically it should work through walls just like your wireless remote phones that are 2.4 GHz as well. Yes, there is 30 day satisfaction guarantee so you would be able to return it in the first 30 days. Good luck, let us know if it works. Note the Transmitter can drive multiple Receivers. WE hope to add a single receiver so it can be purchased separetly along with the WSK100 kit. TL/4131

I have two subwoofers for my home theatre system, how do I connect two subs to my receiver?
1 Answer
Hi Dave: In order to connect both the Sub-woofers with the WSK-100, you have two options, both will need you to purchase 2 each of the WSK-100 kits. The first option you will connect one of the Transmitters to Sub-woofer output #1 and a second Transmitter to Sub-woofer #2. Each Sub-woofer will have its own Wireless Receiver connected to the Powered Sub-woofer with a short RCA cables (single/mono). Note: Both the Transmitter and Receiver come with AC power supply so both the Sub-woofer and Receiver will need to be near a AC outlet or connected to a extension cord. The other option is you can control both Sub-woofers and their wireless Receivers with just a single Transmitter. Unfortunately we do not offer the Receiver by itself, it is only available as part of the kit. One other option, you can connect one sub directly to the AVR and then use a wireless kit to connect the other. I hope that helps TL/3735

How critical is the line of sight requirement? Can it pass through a glass cabinet door? A sofa? Thanks!
1 Answer
Hi Jeff: Think of your wireless phones that were popular before cellphones took over. These were 2.4 GHz as well and would work through some objects. The line of sight is not as critical as IR or Bluetooth wireless devices. Good Luck, we do have a 30 day money back satisfaction guarantee TL/4134

Will this work on a definitive technology super cube ii ?
1 Answer
HI Carl: Yes the WSK100 will work for your application whether you are connecting to a stereo output, Single Sub output or LFE output. The WSK100 features a single input on the Transmitter and single output on the WSK100 Receiver. Your Definitive Technologies Subwoofer features either a LFE (low frequency effects) or stereo input. The LFE will use a mono cable from the AV Receiver to the WSK100 Transmitter and single sub cable from the WSK100 to the single LFE input of the Definitive Technologies Super Cube. If you are dealing with a stereo output you can use an RCA Y adapter 2F to 1M to connect to the WSK100 Transmitter and then use another RCA Y Adapter 1M to 2F and a short RCA patch cable to connect to the Super Cube right and left RCA inputs. Let us know how it works TL/3933
