[. . . ] The high frequencies are handled by a 44XTTM 4" titanium diaphragm compression driver, utilizing ferrofluid cooling, coupled to a CH 7 constant directivity horn. This horn has a smooth, even response with good pattern control. The 44XT driver features the Radialinear Planar Phase Correction System, under US Patent 6, 064, 745, which provides smoother and extended high frequency response. Input connection to the system is made via two 1/4" phone jacks in parallel, and a 4-pin Neutrik switching jack is provided for bi-amping flexibility, while maintaining superior signal integrity. The internal passive crossover features Sound Guard 44 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 fullrange, 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 woofers and horn; the sum total is a clean, clear and smooth response. The lower woofer is rolled off before the mid-range crossover point, so it does not interact adversely with the upper woofer, which operates into the mid-range. High-quality, reliable crossover components include polypropylene capacitors, and linear high current inductors. The optimal integration of the crossover with the selected drivers results in a smooth frequency response from 50 Hz to 19 kHz. A crossover EQ switch is provided to tailor the response in the mid-range, providing a nominally flat frequency response position, and an EQ'd position that pulls the mids back to help keep bright rooms from overloading, or to help achieve a mellower voicing for those applications that prefer it, such as DJ use. With a double 15" woofer based enclosure and a horn-loaded 2" throat compression driver, this system can put out some very serious sound levels, and take 2, 000 Watts program of clean amplifier power, resulting in precise coverage with awesome clarity and high reliability. Frequency response This measurement is useful in determining how accurately a given unit reproduces an input signal. The frequency response of the SP 7X is measured at a distance of 1-meter using a 1 Watt (into the nominal impedance) swept-sine input signal. [. . . ] Box 2898, Meridian, Mississippi 39301-2898.
