I have tried shielding and different tricks for wiring signals but the simplest solution post-build seems to bโฆ

If you're interested in electronics or signal processing, you may have heard of a low-pass filter. A low-pass filter is a circuit that allows low-frequency signals to pass through while blocking high-frequency signals. It's commonly used in audio equipment, communications systems, and power supplies to remove unwanted noise or interference.

Passive RC Filter Tutorial Circuit Diagram
Applications of passive Low Pass Filters are in audio amplifiers and speaker systems to direct the lower frequency bass signals to the larger bass speakers or to reduce any high frequency noise or "hiss" type distortion. Just want some suggestion design low pass filter circuit for my 40w-4ohms speaker as my subwoofer, thanks. Posted on

Cut off frequency of the filter will depends on the values of the components chosen for the circuit design. Cut off frequency can be calculated by using the below formula. f C = 1/ The main usage of the low pass filter circuits is to avoid A.C. ripples in the rectifier output. The low pass filter is used in audio amplifier circuits.
