Since your amplifier undoubtedly has a treble control, you don't
really need those controls anyhow.

Many modern amps do not have tone controls, and they aren't likely to be
optimized for even simple "room acoustics" adjustments.


They're kind of a conceit, I guess, for audiophools who thought
they should "tune" the speakers to their "soundspace" or whatever.

Level controls were on speakers long, long before there were "audiophools".

Some rooms are bright or dull, and require some adjustment from the
speakers. Continuously variable controls were gradually replaced with a two-
or three-position switch. Many modern speakers have no controls at all,
probably because the designers don't want the listener screwing with their
work.

My Apogee Divas have a three-position switch for the supertweeter. They're
also biamped through an electronic crossover that allows small adjustments
(no more the +/- 2dB or 3dB) to be made to the midrange drivers, and what
they call the "rake" -- the gradual rolloff of high frequencies often needed
when playing orchestral recordings. There's a also a control that adjusts
the relative output of the woofer and mid/high drivers.

These controls are extremely useful, to say the least. Don't condemn them if
you're never used them.
