User manual PEAVEY SP 2 DATASHEET

[. . . ] The SP 2 has a trapezoidal-shaped enclosure, which reduces the buildup of standing waves inside the enclosure to minimize midbass and mid-range coloration. It is constructed of nine-ply Baltic birch and covered with a durable black carpet. [. . . ] Sound Guard provides long- and medium-term driver overload protection without impairing musical transients or dynamics on either the mid-range or the tweeter when the system is used full range or when it is biamped. The crossover provides driver roll-off and protection as well as driver EQ for the woofer and horn for a clean, clear and smooth response. High quality, reliable crossover components include polypropylene capacitors and high current inductors. The optimal integration of the crossover with the selected drivers results in a smooth frequency response from 54 Hz to 17 kHz. Despite its compact dimensions, this system can produce very high sound levels and handle 1000 Watts program power, resulting in high articulation and long-term reliability. Frequency Response This measurement is useful in determining how accurately a given unit reproduces an input signal. The frequency response of the SP 2 is measured at a distance of 1meter using a 1 Watt (into the nominal impedance) swept-sine input signal. As shown in figure 1, the selected drivers in the SP 2 combine to give a smooth frequency response from 54 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.
