Dividing Networks

The job of the dividing network is to distribute the various frequencies to
their respective transducers. The network is also designed to complement
component location on the baffle. Slopes are chosen to match the exact
response of each driver in its respective frequency range, as well as to
ensure that the high-frequency transducers are adequately protected from
dangerous low-frequency components.

current, low-distortion operation. All capacitors in the network are
series/parallel connected and operated with D.C. bias. This effectively
enables the capacitors to operate in "Class A" mode, which substantially
increases sonic detail, resolution, and dynamics. The low-frequency section
of the dividing network is mounted on a dedicated circuit board that
separates both electrical and magnetic properties from that of the
midrange and tweeter sections.
