About this product

The JBL® MS-WBC wireless bass control provides shelving bass boost up to +10 decibels at an MS Series amplifier without making you connect any additional wires. The unique shelving-boost functionality of the amplifier’s digital filters ensures that you add linear boost below 60Hz without affecting the low-pass crossover frequency (and never affecting anything above 160Hz) – something that other amplifiers with external bass-boost control cannot promise. An onboard 3-volt CR2025 battery or optional hard-wired connection plug provide the unit’s power.
