PT2350 is a tone control subwoofer cross-over low pass filter chip utilizing CMOS Technology. It features
a tone control range of + 10dB (50Hz, 4 KHz) and subwoofer low pass filter of the second order Sallen
Key Design. The roll-off point can be adjusted by changing the value of the external capacitor.

Don't think you will find pin compatible swapout
