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.


By the rest of your post, you mean the other way around.

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.


Easiest way is to add a resistor in series with each tweeter. Something
about 8 ohm 5 watt should be a good start


True. I used "attenuate" inappropriately. Using resistors would mean I'd
have to dismantle the speakers, or make the job overly complex. I paid $69
for the pair at Walmart and I don't want to screw them up. Seems if I put a
very small inductor in series, it would lower the frequency response. The
effect of the inductor would be more pronounced the higher the frequency,
and less the lower the frequency, such that the difference to bass would be
insignificant, but on the top end it would do what I want.

I just need a value for an inductor.
