pumped air to take its natural path in and out of the cavity. This results in woofers that can
handle higher power with greater reliability than those of conventional design.

HIGH-PASS FILTERS
We strongly encourage the use of an external, active high-pass filter to protect the cone
drivers from excessive low-frequency excursion. A high-pass filter will eliminate the
potential of low-frequency modulation from wind noise, turntable rumble, stage vibration,
and other causes that result in a poorly defined and ‘muddy’ bass response. Additionally, a
high-pass filter will avoid wasting amplifier power by keeping the amplifier from attempting
to reproduce frequencies below the loudspeaker’s intended operating range. The table
below shows the recommended filter settings:
