CROSSOVER ADJUSTMENTS

In most car audio installations, there is a tendency for a “midbass boom.” Because of their interior dimensions, most cars will resonate or ring at these midbass frequencies. If we design the system so there is less musical information in this region, the fin?. response is very smooth and natural sounding.

The REFERENCE300sx incorporates electronic crossover.

The high and low pass portions of the crossover can be set independent of one another.
