Frequency Response

This measurement is useful in determining how accurately a given unit reproduces an input signal. The frequency response of the SSEUB2T 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 UB2T combine with the signal processing to give a smooth frequency response from 160 Hz to 16 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 SSE UB2T exhibits a desirable beamwidth and directivity (figure 3 & 4) suitable for permanent installation 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 for the 8-ohm input 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 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. Speaker can fall if improperly
