[. . . ] The internal passive crossover features Sound GuardTM III tweeter protection circuit, an advanced topology crossover with high performance components, to provide high power handling and reliability. Peavey's proprietary high-frequency driver protection circuitry, Sound Guard, provides long and medium-term driver overload protection when the system is used full-range or when it is bi-amped, without impairing musical transients or dynamics. The crossover provides driver roll-off and protection, as well as driver EQ for the woofer and horn, the sum total is a crystal clear and very smooth response. High-quality, reliable crossover components include polypropylene capacitors, and extremely high current inductors and input connectors. The optimal integration of the crossover with the selected drivers results in a smooth frequency response from 64 Hz to 18 kHz. Despite its compact dimensions for a 15" based enclosure, this system can put out some very serious sound levels, and take 1, 000 Watts program of clean amplifier Harmonic Distortion : 10% Rated Power 130 120 110 dB SPL (re 20 Pa) 100 90 80 70 60 50 20 50 100 200 500 1k 2k 5k 10k 20k Frequency (Hz) 2nd Harmonic 3rd Harmonic Harmonic Distortion : 1% Rated Power 130 120 110 dB SPL (re 20 Pa) 100 90 80 70 60 50 20 50 100 200 500 1k 2k 5k 10k 20k Frequency (Hz) 2nd Harmonic 3rd Harmonic 3 power, resulting in an outstanding amount of clean coverage with amazing clarity. 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. Architectural & engineering specifications The loudspeaker system shall have an operating bandwidth of 64 Hz to 18 kHz. The nominal output level shall be 99. 0 dB when measured at a distance of one meter with an input of one Watt. The nominal impedance shall be 8. 0 Ohms. The maximum continuous power handling shall be 500 Watts, maximum program power of 1, 000 Watts and a peak power input of at least 2, 000 Watts, with a minimum amplifier headroom of 3 dB. [. . . ] As an example, a distortion curve that is down 40 dB from the fundamental is equivalent to 1% distortion. 3 + 2 YEAR LIMITED WARRANTY NOTE: For details, refer to the warranty statement.
