JBL brings you wireless remote control over your system's bass boost. The MS-WBC wireless bass controller communicates with your JBL MS amplifiers without the need to run wires through your vehicle. But it's not just a simple subwoofer bass boost — it also applies a boost to the low midrange speakers, so your system's crossover point remains constant and the overall texture at the boost point sounds smooth.

The MS-WBC cuts or boosts bass frequencies below 60 Hz by +/- 10 dB and works with up to four JBL MS amps simultaneously. It runs on batteries, but also includes a power cable if you want to hardwire it into your vehicle.

Must Have for your Sub - Highly Recommend!

Written By Bones, Charlottesville, VA on Monday, January 27, 2014

As my title suggests, this little gizmo is a must have item for your sub... particularly if you can't reach the volume control. For me, I like a broad variety of music and the bass level for Eminem isn't the same as the bass level I would choose for, say, Neil Young. It is incredibly handy to have a bass control knob at hand. This one is wireless so no wires to manage either.

Pros: Great convenience. Very responsive. Takes you from zero bass to back-tire-lifting-sonic-thumping at the turn of the dial.

Cons: Slight delay in registering with the sub... you get used to it but when I first turn the car on, it's default is wide open!... you need to just touch the unit and it goes back to your current setting.

Product Research


Overview: Designed for use with JBL MS-series amplifiers, the MS-WBC wireless bass control lets you precisely raise or lower the bass output of your car audio system without altering the character of the sound. Conventional bass controls work by changing the system's crossover frequency, which affects overall frequency response. But the MS-WBC lets you dial bass output up or down by up to 10dB without changing frequency response. An RF remote that installs in minutes with just a screwdriver, the MS-WBC works with the JBL MS-series amps in your system, letting you set the perfect amount of bass for any recording or source.

Compatibility: The JBL MS-WBC wireless remote control is compatible with JBL MS-series amplifiers (MS-A1004, MS-A5001).

Wireless RF Remote: The JBL MS-WBC is an RF (radio-frequency) remote control that communicates with JBL MS-series amplifiers without wires.

Bass Boost (60Hz, +/-10dB): The MS-WBC lets you adjust the bass output (around 60Hz) from the JBL MS-series amp in your system up/down by as much as 10dB, right from the driver's seat, without changing frequency response or altering the character of the sound.

Battery Powered: The MS-WBC will operate for years on the pre-installed CR2025 battery; or you can hardwire it directly to your car's 12V battery (using the supplied power/ground cable.
