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 ability to boost or attenuate the sub level when an amp and subwoofer are connected to the subwoofer pre-amp output.

Variable Bass Boost

Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.

Variable High Pass Filter

Variable high-pass filter gives you control over the frequencies that pass through to the full range speakers.

Variable Low Pass Filter

Variable low-pass filter gives you control over the frequencies that pass through to the subwoofer.

I bought this for my brother . he have 3 15's on a boss 5000 watt amp with 4 6x9's on a boss 800 watt amp so I thought the crossover would be a great help and it was it made the bass deeper and the highs higher so all in all a great buy

Looked nice but didnt work. Every time I would touch it or try to tune it there was a loud popping sound like it had a short of some kind. I checked all my grounds and connections and after a lot of trouble shooting I pulled the crossover and put in my old RadioShack one and everything worked perfectly.
