I purchased an in-dash stereo for my pick-up truck, and some cheap speakers.
The stereo has bass and treble adjustment but not midrange. I have since
replaced the speakers. The new ones do better, and sound better, but still
have the same problem. High frequencies have too much attenuation. Reducing
treble all the way will not kill the cymbals and S sounds. With the new
speakers, if I turn the bass up very much, I get incredible deep bass, but
still too much high frequency.

I thought I would buy some inductors at Radio Shack and put in line with the
speakers. From what I remember they are measured in henrys. But, I need so
little effect I may be better off making small wire coils, instead.

To avoid much trial and error, would someone please suggest a starting
point? I might buy several inductors either side of that and see what they
do. Thanks
