for the voice coil, and the airflow director causes the air to pass in close proximity to the
former. By directing the air to flow over the hot aluminum former, more heat is removed from
the voice coil than simply allowing the 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:
