Commentary
A dividing network designed for the 2150.
The crossover frequency is set to 1.2 kHz.
It consists of high-quality components such as high-voltage non-polar capacitors, individually calibrated low-loss inductors, resistors and switches that can withstand severe use.
The network employs a circuit with a cutoff characteristic of 12dB/oct, and an impedance correction circuit is employed for the low frequency to obtain the crossover frequency accurately.
