BX-10 | Digital Bass Reconstruction Processor – Precision Bass Control for Every Ride

Legacy

Bass Reconstruction Processor  SWEEP: selects the frequency boosted by the equalizer. This is the “center frequency,” which can be as low as 27Hz or 63Hz. Choosing this frequency depends on your taste in music. WIDTH: increases or decreases the bandwidth range, or “Q,” boosting frequencies near the “center frequency.” Narrow Q focuses on harmonics immediately surrounding the center frequency. Wide Q unlocks harmonics all around the center frequency. DASH CONTROL: included with this bass processor can be mounted anywhere in the vehicle, but easy adjustment from the driver seat is recommended. The output level of the Bass Equalizer can be controlled.
