molded fiberglass and shall include a 3 stage multiple mesh filter system
for weather and rodent resistance:
A. Large 20-gauge perforated aluminum screen on front mouth
assembly.
B. 100 x 100 weave stainless steel mesh between HF horn and
HF driver.
C. 100 x 100 weave stainless steel mesh over 15" woofer.
