enclosure is made from very high impact
injection-molded polypropylene in a
trapezoidal shape, with extensive ribbing
and bracing, and the grilles utilize perforated
metal protected by a high quality vinyl
coating process, and has an integral foam
inner layer for environmental protection.

woofer with a 4"
voice coil, and a water-resistant treated
cone and dust cap for superior
environmental stability. Capable of over
500 W of continuous power handling (AES
Std 2-1984), the woofer can handle a lot of
sheer power. The high frequencies are
handled by an RX

Utilizing Quadratic Throat Horn
technology, under US Patent 6,059,069, the
horn has lower distortion than many popular
CD horn geometries. The RX 22 driver
utilizes the Radialinear Planar Phase

The internal passive crossover features
Sound Guard
™
III tweeter protection circuit,
an advanced topology crossover with high
performance components, to provide high
power handling and reliability. Peavey’s
proprietary high-frequency driver protection
circuitry, Sound Guard, provides long and
medium-term driver overload protection
when the system is used full-range or when
it is bi-amped, without impairing musical
transients or dynamics. The crossover
provides driver roll-off and protection, as
well as driver EQ for the woofer and horn,
the sum total is a crystal clear and very
smooth response. High-quality, reliable
crossover components include
polypropylene capacitors, and extremely
high current inductors and input connectors.
The optimal integration of the crossover with
the selected drivers results in a smooth
frequency response from 76 Hz to 18 kHz.

Despite its compact dimensions, this
enclosure can put out some very serious
sound levels, and take 1000 Watts program
of clean amplifier power, resulting in an
outstanding amount of clean coverage with
amazing clarity.
