The powered loudspeaker system shall have a frequency response from 60 Hz to 20 kHz. The peak SPL with
inaudible distortion shall reach 127 dB with music as a source, when measured at a distance of 1M and driven
to full output capacity. The system shall utilize a Peavey
Pro 15 15" heavy-duty woofer and a Peavey RX
14 1.4"
®
titanium diaphragm dynamic compression driver. The nominal radiation pattern shall be 100° in the horizontal
plane, and 50° in the vertical plane. Axis of the vertical main polar lobe is angled down 10 degrees, resulting in
the angular pattern with respect to straight ahead being +15, -35 degrees.
The powered, bi-amplified loudspeaker system shall have an input channel consisting of a medium impedance
input connector consisting of one combo female XLR and 1/4" TRS phone jack on the rear panel.
The input section shall have a Contour EQ system activated by a pushbutton that provides for boost at the low
and high frequencies of about 5 dB relative to the midrange.
There shall be a group of Thru (output) connectors consisting of a male XLR jack, and a 1/4" TRS phone jack.
The system power amplifiers shall have an unfiltered frequency response of 20 Hz to 20 kHz which deviates no
more than +0, -3 dB up to rated power, a damping factor greater than 100 @ 1 kHz into 8 ohms, hum and noise
better than 90 dB below rated power, and THD and IMD of less than 0.5%.
The woofer amplifier shall be capable of 325W continuous before thermal pull-back to into an 8 ohm nominal load,
and the tweeter amplifier shall be capable of 75W continuous output into a 8 ohm load, and both shall incorporate
independent DDT
compression.
The input signal shall be electronically divided into high frequencies and low frequencies by a staggered
pole fourth order slope line-level crossover at 2.8 kHz. The low frequencies shall be processed to provide
bass boost, subsonic filtering and overall response shaping, and the high frequencies shall be equalized for
response-shaping.
The enclosure shall be constructed of injection-molded ABS with a UL flame rating, and reinforcing ribs
internally. A handgrip shall be incorporated on each side near the woofer and towards the front, and on the
right side of the cabinet.
A separate powder-coated metal grille shall be provided for horn and woofer protection. The cabinet shall
incorporate a pole mount for speaker stand use, four tall sturdy rubber feet for floor standing use, and a group
of four mounting point inserts on the top and bottom each, and on the right side, for flying use.
The outside dimensions shall be: 28.25" (71.8 cm) tall x 18.90" (48.0 cm) wide x 18.71" (47.5 cm) deep, and the
weight shall be 51 lbs. Power requirements shall be: 370 Watts nominal, 100-120 VAC, 50/60 Hz Domestic and
220-240 VAC, 50/60 Hz (Export). The loudspeaker system shall be called a Peavey PVXp
