(67. 7 kg) Features · Two 1505-8KADT Black Widow woofers · 44XTTM compression driver · Sound GuardTM 44XTTM high frequency protection circuit · Trapezoidal enclosure design · Built-in pocket casters for easy transport DESCRIPTION The Peavey SPTM 7G is a newly designed quasi-three-way speaker system comprised of two 15" Black Widow woofer/midrange, and a 44XT compression driver coupled to a CH 7 constant directivity horn. [. . . ] As with all SP full-range speakers, this unit can be driven in full-range or biamp mode simply by plugging into the desired jack on the input plate. The CLASSIC 810 TX has a trapezoidal shaped cabinet, rather than the more traditional rectangular shape. This allows cabinet arrays to be constructed more easily. This shape also greatly reduces the build-up of internal standing waves. Standing waves are internal amplitude peaks that occur due to reflections within the cabinet at frequencies related to the internal square dimensions of the cabinet. The trapezoidal shape resists the formation of standing waves by causing the internal reflections to cancel rather than reinforce each other. This ensures a minimum of mid-bass and mid-range coloration of the reproduced sound due to standing waves within the cabinet. The CLASSIC 810 TX is constructed of very high quality 3/4" Oriented Strand Board (OSB), which is a void-free, medium density, and wood-species specific material. (This material should not be confused with lesser quality materials which possess internal properties of OSB, and are commonly known as "chip-board" or "wafer-board". Peavey Electronics rates this unit's system power handling using a modified form of the AES Standard 2-1984. Utilizing audio band limited (20 Hz - 20 kHz) pink noise with peaks over 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. The test signal contains large amounts of very low frequency energy, effectively simulating the frequency content of live music situations. The full measure of high frequencies in the test signal allow for exposure of the speaker system to synthesized tones that may extend beyond audibility. This rating is contingent on having a minimum of 3 dB of amplifier headroom available so as to ensure that clipping does not occur. ARCHITECTURAL & ENGINEERING SPECIFICATIONS The loudspeaker system shall have an operating bandwidth of 50 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 4. 0 ohms. The maximum continuous power handling shall be 600 watts, maximum program power of 1, 200 watts and a peak power input of at least 2, 400 watts, with a minimum amplifier headroom of 3 dB.
