Commentary
A dividing network with a crossover frequency of 7 kHz.
It is designed for 3-way use with driver 2440. You can extend the high range by adding a tweeter to a 16 Ω driver.
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.
Equipped with an attenuator with variable volume.
