Hi,

I've seen people adding JBL hi freq driver (2402, 2405 etc.) to horn speakers by connecting a capacitor in series to the +ve terminal of the driver.

May I know:

1. Whether the capacitor in series is performing the freq cut off function

2. If so, may I know the value of the capacitors to achieve 18 khz, 20khz and 22 khz crossover respectively?

Thanks.
