SPL Crossover

It is difficult to optimally integrate bass loudspeakers or subwoofers. At present, there are almost only digital crossovers for this purpose. But who wants to convert back and forth You don’t need to anymore. Our Crossover sets the crossovers anew.

The crossover is divided into two section: The LowA section for the bass loudspeaker or subwoofer (mono or stereo) and theA Mid-HiA section for the top/main speakers.

The crossover frequencies for LowA and Mid-Hi can be set individually from 50 Hz to 120 Hz in 6 positions.

The LowA filter has a slope of 24 dB per octave. The slope of the MID-HI filter can be switched from 12 dB (Butterworth) to 24 dB (Linkwitz/Riley).

Audio signals should come from the top speakers and bass loudspeakers or subwoofers in phase. The crossover offers variable phase control for this purpose.

Use the toggle switch to activate the phase control (phase 0A° or phase -180A°) and use the control to establish simultaneousness.

If the phase control is not required, it can be switched off and thus disappears completely from the signal path.

If you want to connect two bass loudspeakers or subwoofers (one for L and one for R), this switch should be set to stereo.

If you only use one bass loudspeaker or subwoofer, switch to mono. The crossover creates a mono signal of the Low frequencies and outputs it to both Low outputs (L + R).
