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

NOTE: The following formula may be used to determine values in creating
resistor packs. The frequency is equal divided by the
resistor value, or 1.600.000 ohms X To make a custom
use 4 identically valued resistors of 2% or tighter tolerance. See
drawing of P. information.
