Frequency Response, Directivity, Power Handling

array [see limitations under mounting instructions]. Both versions of the ILS 1294 are solidly constructed of 3/4" void free poplar plywood and finished with an exterior grade hardened black paint.

Frequency Response

This measurement is useful in determining how accurately a given unit reproduces an input signal. The frequency response of the ILS 1294V 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 ILS 1294V combine to give a smooth frequency response from 63 Hz — 18.5 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 are 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 ILS 1294V 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. This rating is contingent upon having a minimum of 3 dB of amplifier headroom available.

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.

Mounting

Caution: Before attempting to suspend this speaker, consult a certified structural engineer. The speaker can fall from improper suspension, resulting in serious injury and property damage. Other enclosures may be suspended below one ILS 1294V. However, the combined weight of additional enclosures and all cables, clamps and other hardware must not exceed 330 pounds. The ILS 1294V weighs 70 pounds and the maximum combined weight suspended from the uppermost mounting bracket assemblies must not exceed 400 pounds. The maximum enclosure angle is 45o. Use only the correct mating hardware. All associated rigging is the responsibility of others.
