Description

The latest version of the SP™ 1 has the new BWX high power Black Widow woofer incorporated, as well as a very nice looking cabinet design. The SP 1X is a two-way speaker system comprised of a 15" Black Widow BWX woofer with a Kevlar® impregnated cone, and a 44XT compression driver loaded onto a CH® 7 constant directivity horn.

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 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 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

56 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.

Despite its compact dimensions for a 15" based enclosure with a 2" throat compression driver, this system can put out some very serious sound levels, and take 1400 Watts program of clean amplifier power, resulting in precise coverage with excellent 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 1X 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 1X combine to give a smooth frequency response from 56 Hz to 19 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

The SP 1X has a trapezoidal shaped enclosure, which reduces the build-up of standing waves inside the enclosure, which minimizes mid-bass and mid-range colorations due to the cabinet. It is constructed of 3/4" void-free plywood and is covered with a durable black carpet. The enclosure corners are reinforced with polymer caps, and a black powder-coated expanded metal grille covers the lower half of the system to protect the woofer from external damage. An SA-1 stand mount adaptor is built-in for ease of

speaker stand use.

The two-way system is comprised of a 15" Black Widow BWX woofer with a Kevlar impregnated cone, and a water- resistant treated cone and dust cap for superior environmental stability. Capable of over 500 W of continuous power handling (AES Std 2-1984), the woofer can handle a lot of sheer power. The high frequencies are handled by a 44XT 4" titanium diaphragm compression driver, utilizing ferrofluid cooling, coupled to a
