Satellite + Subwoofer 3-Speaker System Electronics Crossover IC

PT2353

The subwoofer in this 3-speaker system has only one channel output; therefore, it is recommended

that the LPF must be less than 300Hz. If the frequency is greater than 300 Hz, then the audio output is

can be clearly discernible. That is, it is easy to know where the sound is coming from. The following

diagram provides the suggested crossover frequencies and respective external capacitors.

Notes:

⎯⎯⎯

Crossover Frequency: 280Hz, C=0.015

- - -

Crossover Frequency: 200Hz, C=0.022

— —

Crossover Frequency: 120Hz, C=0.033

C is the High Pass Filter External Capacitor.

C1 and C2 are the Low Pass Filter External Capacitors
