Reducing midrange

[qguy]

the midrange of my 2 way bookshelves is a little bit too forward for my taste, Can you direct me or show me a circuit for a passive x-0ver that would reduce the midrange output of my woofer in the 800-1200 range in 2db,4db,6db increments - thanks

This is just what I came up with googling for "passive notch filter":

I hope that's a helpful start.

Im looking for something that does the opposite.

However how do you make it so it doesnt attenuate frequencies outside the bandwidth range?

Take it apart and look inside. You may be able to modify the crossover with some low cost parts to achieve what you want.

I found a LCR circuit that uses the same woofer (usher 8945 ) that reduces the 900hz, the circuit calls for an inductor with a 1.0 mh value, I reckon I have to do my own winding, I found a calculator that addresses the gauge and number of turns, are there any advantage of using a thick wire vs a thin magnetic wire other than cost and size ?
