Description

The Crest LQ 10 is an injection-molded two-way speaker system,
engineered in the Crest 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. The grille is comprised of
perforated metal protected by a high quality vinyl coating process.
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 Crest
HF TM 1 one and a quarter inch titanium diaphragm compression driv-
er, 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 TM technology, under US Patent 6,059,069, the
horn has lower distortion than many popular CD horn geometries.
Input connection to the system is made via two 4-pin Neutrik® jacks
connected in parallel for full-range signal input and daisy chaining
capability
The internal passive crossover features the DPS TM (Dynamic
Protection System) tweeter protection circuit, an advanced topology
crossover with high performance components, to provide high power
handling and reliability.The crossover provides driver roll-off and pro-
tection, as well as driver EQ for the woofer and horn. High-quality,
reliable crossover components include polypropylene capacitors,
and high current inductors and input connectors. The optimal inte-
gration of the crossover with the selected drivers results in a smooth
frequency response from 74 Hz to 18 kHz.
