There have been suggestions that a multi-band equalizer would do the same
as a mid/high replacement for improving mid/high performance.  BUt if a
tweeter drops off sharply at, say 16kHz, wouldn`t a lot of boost above
that just increase distortion--or at least, increase distortion while
increasing output?

My receiver has a mid-range tone control which I use, in addition to
Bass & Treble controls, to produce what I think is realistic sound.
To apoint, the mid-range control is OK but after only a couple of dB
of boost, the effect becomes very UNrealistic (probably due to the
broad frequency range affected by the control, or the contour over the
range).  Boosting the treble, however, produces nasty sound with even
a little boost.  Wouldn`T the really fundamental way to improve
loudspeaker response be to build the best loudspeakers anyway?

I know there are electronic dynamic-feedback loudspeaker systems, and
systems that have their electronics carefully tailored to overcome
measured speaker deficiencies (the BBC has at least one monitor system
like that) but in these cases the whole thing is done from a systems
approach.

I`ve always felt that multi-band equalizers, sold to "improve room response"<
were yet another gimmick (although they probably could work to eliminate
unfortunate resonances and dead spots for exactly one place in a room);
to overcome loudspeaker response problems---?
