Bass and treble ? I have a design that will blow your mind.
If your public email is good I'll send you the print. Once I find it.

My email in the signature works. However, please don't send me your
design. I'm not into audio (pro or prosumer) and really don't have
the time to look at it, analyze it with LTSpice, critique it, build
it, or test it. Good luck with your design.
