Hi. Nice job here Wahyu with all your posts. Do you have an active High Pass and Low Pass filter for a 2.1 system?

thanks,
Adrian

Hello andrian.

Do you search for 2.1 speaker system? You can find here about low and high pass filter. You can combine it into your 1 amplifier for subwoofer and 2 amplifier circuit for mid and high tone.
