DIY audio filter. suggestions and advice

hey guyz,
I recently found online some circuit diagrams of audio filters and I was wondering whether it would be feasible to make such a circuit for DJ use.
despite having a masters degree in engineering (aeronautics), I seem to be clueless when it comes to electronics… thus I would like some tips and advice on this project.
has anyone tried building a filter? is it worth the time?

any help would be greatly appreceiated!

Heres a good start for a lowpass filter.
