Frequency response

This measurement is useful in determining how accurately a given unit reproduces an input signal. The frequency response of the SSE 12 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 SSE 12 combine to give a smooth frequency response from 79 Hz to 17 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 specifications provide a reference to the coverage characteristics of the unit and provide insight into proper placement and installation in the chosen environment. The blending of the components of the SSE 12 exhibit a desirable beamwidth and directivity (figures 3 & 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 & 6 for two power levels. Ten percent (10%) of rated input power and either one percent (1%) of rated input power or 1 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 or mount this speaker, consult a certified structural engineer. The speaker may fall due to improper installation, resulting in serious injury and property damage. DO NOT suspend or mount any other product or device from this enclosure. The maximum enclosure angle is 45°. Use only Grade 5 hardware or better. All associated rigging is the responsibility of others.
