Description
The Quadra
™
10 is an injection-
molded, two-way speaker system,
engineered in the AA tradition to provide
superior performance from a compact and
durable package. The enclosure is made
from very high impact, injection-molded
polypropylene in a trapezoidal shape, with
extensive ribbing and bracing, and the grills
utilize perforated metal protected by a high
quality vinyl coating process, and has an
integral foam inner layer for environmental
protection.
The two-way system is comprised of a
10" long throw heavy-duty woofer, and a
water-resistant treated cone and dust cap
for superior environmental stability. The high
frequencies are handled by a 14XT
™
1.4"
titanium diaphragm compression driver,
coupled to a 1" Quadratic Throat Geometry
horn, molded integral to the cabinet. This
horn provides outstanding dispersion
coupled with a well-controlled pattern, and a
smooth, even response.
Utilizing Quadratic Throat Horn
™
technology, under US patent 6,059,069, the
horn has lower distortion than many popular
CD horn geometries.
