Looking for Very good tone control schem.

This Fletcher Munson Passive frequency contour circuit can be used to generate listening goose bumps even at child safe 74 db levels. I use steep LR8 active crossovers to showcase voice on one 80-3,000Hz speaker, and an active version of the F-M contour adds body at low SPLs.

The science behind Fletcher Munson helps to explain many audiophile addictions to plaster cracking SPLs. heh---could you speak up.

Holman and Kampmann

Dear mlloyd1,
that tone control was published in Tomlinson Holman and Frank Kampmann paper "Loudness Compensation: Use and Abuse" AES 1978, July
They used extra follower Q1, thus prevent interaction between treble and bass controls completely
