Adjustable Lowpass Filter Circuit


Gliderguy

Recommended Posts

I would like to build an outboard adjustable low pass filter for my RSW15.

I want to be able to leave the RSW set to LFE for HT use but also have a full range signal from a preamp available through the outboard LP filter. Right now I have to switch from LFE to the LP filter when running the sub for music.

Basically I am looking for a circuit schematic and parts list to mirror the RSW's LPF.

Any recommendations?

Thanks
