Filter Design to Boost Bass for Full-Range Speaker

[poynton]

Hi.

I have been searching, without success, for a simple filter circuit to boost the bass response of a full range speaker.

I have found many low pass filters for subs and active xovers but not with the response curve as below.

I want about 6dB boost @ 12dB/octave from say 150Hz down to 20Hz with a sharp cutoff @24dB/octave. I/O at line level.

Any ideas??

Thanks

Andy

Hi, 4 octaves at 12dB/octave = 48dB. 😉/sreten.

Look back, and see project 84 - constant Q, eight band bass EQ
