Input connection to the system is

made via screw terminal strip (one pair) for

full-range inputs.

The internal passive crossover

features Sound Guard^™II 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

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 high

current inductors and input connectors. The

optimal integration of the crossover with the

selected drivers results in a smooth

frequency response from 74 Hz to 18 kHz.

Despite its compact dimensions, this

enclosure can put out some very serious

sound levels, and take 500 Watts program

of clean amplifier power, resulting in an

outstanding amount of clean coverage with

amazing clarity.

Frequency response

This measurement is useful in

determining how accurately a given unit

reproduces an input signal. The frequency

response of the Quadra 10 is measured at a

distance of 1-meter using a 1 Watt (into the

nominal impedance) swept-sine input signal.

As shown in figure 1, the selected drivers in

the Quadra 10 combine to give a smooth

frequency response from 74 Hz to 18 kHz.

Directivity

Beamwidth is derived from the -6 dB

points from the polar plots (see figure 3)

which are measured in a whole space

anechoic environment. Q and Directivity

Index is plotted for the on-axis

measurement position. These are

specifications that provide a reference to the

coverage characteristics of the unit. These

parameters provide insight for proper

placement and installation in the chosen

environment. The blending of the

components of the Quadra 10 exhibit a

desirable beamwidth and directivity (figure 3

and 4) suitable for sound reinforcement

applications.

Power Handling

There are many different approaches

to power handling ratings. Peavey rates this

loudspeaker system’s power handling using

a full-range form of the AES Standard 2-

1984. Using audio band 20 Hz to 20 kHz

pink noise with peaks of four times the RMS

level, this strenuous test signal assures the

user that every portion of this system can

withstand today’s high technology music.

high by 14.00 inches wide by 13.19 inches

deep. The weight shall be 31 pounds.

The loudspeaker system shall be an

Architectural Acoustics model Quadra 10.

Architectural and Engineering

Specifications

The loudspeaker system shall have an

operating bandwidth of 74 Hz to 18 kHz.

The nominal output level shall be 96.0 dB

when measured at a distance of one

meter with an input of one Watt. The

nominal impedance shall be 8.0 Ohms.

The maximum continuous power handling

shall be 250 Watts, maximum program

power of 500 Watts and a peak power

input of at least 1,000 Watts, with a

minimum amplifier headroom of 3 dB.

The nominal radiation geometry shall be

90 degrees in the horizontal plane and

40 degrees in the vertical plane. The

outside dimensions shall be 18.75 inches

Harmonic Distortion

Second and third harmonic distortions

vs. frequency are plotted in figures 5 and

6 for two power levels, ten percent (10%)

of rated input power and either one

percent (1%) of rated input power or one

Watt, whichever is greater. Distortion is

read from the graph as the difference

between the fundamental signal

(frequency response) and the desired

harmonic. As an example, a distortion

curve that is down 40 dB from the

fundamental is equivalent to 1% distortion.
