Frequency Response, Harmonic Distortion, Mounting

Frequency Response

This measurement is useful in determining how accurately a given unit reproduces an input signal. The frequency response of the

SP 5 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 SP 5 combine to give a smooth frequency response from 69 Hz to 17 kHz.

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 3 & 4 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

This unit is not designed for overhead suspension. The

SA-1 stand-mount adapter may be incorporated, and four large rubber feet are included on the bottom for floor use.
