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

To e-mail, change noise into sound.

I used resistors for setting the tweeter levels but ran into a little
quirk. The added resistance changed the crossover frequency but more
importanly, it messed up the damping which sounded like ('cause it was)
ringing. The cure was to add a second resistor in parallel with the
tweeter.
