vide ultra-high performance in a portable,

compact, weather-resistant package. The

enclosure utilizes high-impact polypropy-

lene in an injection-molded plastic trape-

zoidal shape, along with a coated perforat-

ed metal grille to offer a cosmetically ele-

gant yet durable system.

The two-way system includes a 15"

Black Widow®woofer with a Kevlar®

impregnated cone and a specially treated

surround, cone and dust cap for excellent

weather resistance. The RX™22 compres-

sion driver features a 2" titanium

diaphragm, a patented phase plug (U.S.

Patent # 6,064,745), and is coupled to an

extremely smooth and well controlled con-

stant directivity horn, with a coverage pat-

tern of 90 degrees by 45 degrees that is

molded into the enclosure. Input connec-

tion to the system is made via 1/4" phone

jacks (2) or 4-pin Neutrik®Speakon®con-

nectors. Provisions for biamplification are

made through a 4-pin Neutrick switching

jack. The internal passive crossover fea-

tures Sound Guard™to protect the tweet-

er, and utilizes high performance compo-

nents and an advanced topology

crossover to provide high power handling

and a smooth yet clear response. The

optimal integration of the crossover with

the selected drivers results in a smooth

frequency response from 60 Hz to 18 kHz.

The free-flow vented cabinet offers

mounting point inserts top and bottom as

well as a molded-in stand adapter for

maximum utility and ease of use.

FREQUENCY RESPONSE:

This measurement is useful in deter-

mining how accurately a given unit repro-

duces an input signal. The frequency

response of the Impulse 1015 is mea-

sured 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 Impulse 1015 8

ohm combine to give a smooth frequency

response from 60Hz - 18 kHz.

DIRECTIVITY:

Beamwidth is derived from the -6 dB

points from the polar plots (Figure 3)

which are measured in a whole space

anechoic environment. Q and Directivity

Index are plotted for the on-axis measure-

ment position. These are specifications

that provide a reference to the coverage

characteristics of the unit. These parame-

ters provide insight for proper placement

and installation in the chosen environ-

ment. The blending of the components of

the Impulse 1015 8 ohm exhibit a desir-

able beamwidth and directivity (Figure 3

and 4) suitable for sound reinforcement

applications.

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.

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. This rating is contin-

gent upon having a minimum of 3 dB of

amplifier headroom available.
