Boss Audio BX55 2/3-Way Pre-Amp Electronic Crossover w/ Remote Subwoofer Level Control

Bass Boost
This feature is built-in to the amplifier and allows you to adjust the amount of bass going to your subwoofers or speakers. Depending on the amplifier the adjustments range is from 0 to 12dB or 0 to 18dB.
Crossover Filter
Built-in crossovers enable you to tailor the audio to your system’s needs. A High-Pass filter allows only the frequencies above the set frequency to pass through to your full range or component speakers and a Low-Pass filter allows only the frequencies below the set frequency to pass through to your subwoofers so your speakers and subwoofer[s] can perform more efficiently and effectively.
Phase Control
The phase control feature allows you to adjust the speakers phase to ensure all audio signals are playing together rather than against each other. When bass notes are noticeably absent, a quick and easy adjustment to the phase control could provide the perfect remedy.
Subsonic Filter
A subsonic filter is designed for use on subwoofers. Since not all subwoofers can reproduce the same low frequencies, the subsonic filter can be set for optimum bass response in order to keep the driver playing efficiently.
Subwoofer Level Control
The wired remote subwoofer level control, mountable for easy access, has long been a popular feature on many of our amplifiers. The remote allows you to control the output level of the subwoofer(s) as needed for optimum sound according to your personal taste and listening environment.
