Bandpassing the Midrange

•The Fanatic Component Systems are optimized for full range music reproduc- tion. In cases where a subwoofer is used, the midrange can be bandpassed in order to prevent overlapping frequencies from the midrange into the subwoofer.

1.Determine the frequency range that the subwoofer will play (i.e.: 20Hz-80Hz)

2.Use the low-pass crossover frequency of the subwoofer system (i.e.: 80Hz) as the high-pass crossover frequency for the midrange

3.Select the appropriate capacitor value (i.e.: 500μF) to properly bandpass the midrange

4.Place the capacitor in series with the “+” terminal of the speaker
