●Principle of Tri-mode
Method of frequency band division using a coil and capacitor…in case of 6dB/oct. slope

●Example:
When it is required to set a crossover frequency of 120 Hz using speakers with an impedance of 4 ohms.
Prepare
2CAUTION
•If you wish to
•Be sure to connect capacitors to speakers to which high frequencies will be passed. Failure to do so will result in a drop of the combined impedance with the subwoofer.
•Ensure that the withstand voltage and current ratings of the capacitors (C) and coils (L) are sufficient.
