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.

NOTE: The following formula may be used to determine values in creating ?ustom” resistor packs. The frequency is equal to 1,600,OOO divided by the Chdiv;dual resistor value, or 1.600.000 I R ohms = X HI. To make a custom
