above 5kHz if a 12dB per octave
crossover is used and at or
above 3.5kHz if you are using an
18 or 24dB per octave crossover.

directly to the 08GTi tweeter is
125 Watts RMS. In fact, due to
the nature of music, and the
reduced energy present at high
frequencies, there is little reason
to use an amplifier larger than
50 Watts per channel on the
tweeter, regardless of the
power of other speakers in
the system.
