Froma reliabilitystandpoint,
this
zonerepresents
a very comfortable operating power range for
each driver. This level
of
power will not stress
the
woofer
but
will
not
extract all
of
its performance
potential, either.
Use
of
less

the

power level will
not
damage
the
woofer,

may result
in
unsatisfactory performance.

Th
