When using an ‘active’ configuration, the tweeter is driven directly by a power amplifier, so care
must be taken not to damage it with inadvertent amplified ‘clicks’ – because it does not have a
traditional passive crossover filter to protect it. The safest solution is to use a high quality film
capacitor to block low frequencies and DC from damaging the tweeter. However, unless there is
any DC voltage (e.g. loud ‘clicks’) from the power amplifier this is usually not necessary because
the DEQX-Cal software provides a High Pass filter for the swept frequencies used to measure the
tweeter. The single pole (6dB/octave) high-pass filter defaults to 750Hz, sufficient to protect most
tweeters intended to operate above say 2K-3K. Contact [e-mail] if in doubt about the
setting required for your tweeter.
