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.

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.

1015 specifications

The Peavey 1015 is a powerful and versatile speaker cabinet that has gained recognition among musicians for its exceptional sound reproduction and reliability.
