overloading the HF section when bi amping?
Yes.
We had a crappy sound tech in a band I was in. He constantly blew out
the tweeter diaphragms. Everybody else thought he was great though, I
and couldn't get a consensus to fire him.
If your speakers are set up for biamping follow the manufacturer's
recommendations. If there are no recommendations then I'd ask them for
some.
This may help:
Bi-amping, or biamplification, is used mainly in professional sound
reinforcement applications, where extremely high levels of loudness
are required. Here big, separate amplifiers powering the low
frequencies, and smaller amps for the midrange will increase overall
output. Sometimes they will use a separate outboard electronic
crossover (the speaker's internal crossover is disabled or bypassed
entirely) so the operator can vary and adjust individual crossover
frequencies, tailor the "slope" of the crossover to match the
strengths of each set of drivers, and also adjust the relative sonic
balance of bass, midrange and treble to suit the environment. This is
important for huge auditoriums or outdoor events where separate arrays
of treble and midrange horns are operating with big "bass bins," but
such systems have no place in domestic home theater systems in normal
rooms. Additionally, it puts control of the relative smoothness and
tonal balance into the hands of the sound system operator, a dangerous
tool for all but the most experienced sound reinforcement experts. It
also partly explains why the live sound at so many concert events (not
all, mind you) is so awful.
(i.e. and also why we blew so many diaphragms.)
