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.

For the Century Gold system, we chose our Charge-Coupled Linear DefinitionDividing Network. The inductors are all designed for high- 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.

Additionally, the Century Gold’s dividing network allows for passive, bi-wire, passive bi-amp, and full active bi-amp operation. For the full active bi-amp mode we recommend the use of a high-quality electronic crossover.
