Subwoofer Low Pass Filter using Transistors The circuit diagram exhibits an active low-pass filter layout that can be assigned any preferred cut-off point, across a large range easily by computing a couple of magnitudes for four capacitors. The filter includes an RC -network and a pair of NPN/PNP BJTs.
Subwoofer active low pass filter - ElectroIMC
https://www.electroimc.com/en/doc/projects/audio/1_subwoofer_active_low_pass_filter
This article presents a simple second order active low pass filter with an adjustable cutoff frequency between 20 Hz and 200 Hz. The circuit, which uses a single power supply, works on low power audio signal (that is, line audio levels) and is intended as a filtering element before a power audio amplifier driving a subwoofer loudspeaker.
