The new SP2 features the Peavey Quadratic Throat Waveguide with an RX™ 22 compression driver loaded onto the constant directivity waveguide. The SP2 is a two-way speaker system comprised of the new 15” Black Widow BWX SF series woofer with a Kevlar® impregnated cone.

The SP2 has a trapezoidal-shaped enclosure, which reduces the buildup of standing waves inside the enclosure to minimize midbass and mid-range coloration. The enclosure is constructed of aspen hardwood plywood augmented with dual-layer top and bottom panels, covered with a heavy duty, textured black Hammertex™ covering and reinforced with high-impact plastic corners. A fulllength, wrap-around perforated steel grille protects the front of the enclosure. An SA-1 standmount adapter is incorporated to accommodate a speaker stand. The two-way system consists of the following driver components: a 15” Black Widow BWX SF series woofer with a Kevlar impregnated cone and dust cap. The woofer is capable of over 500 Watts of continuous power handling (AES Std 2-1984). The high frequencies are handled by a 2” RX™22 titanium diaphragm compression driver utilizing ferrofluid cooling. This superb driver is coupled to a Quadratic Throat Constant Directivity Waveguide (U.S. Patent #6,059,069) to provide smooth, even response, low distortion and good high frequency dispersion. This horn has an asymmetrical vertical polar response, aiming the main energy lobe down 10 degrees so it reaches the audience instead of over their heads. This reduces ceiling reflections and ensures greater clarity and gain before feedback. The RX™ 22 driver features the Radialinear Planar Phase Correction System (U.S. Patent #6,064,745), which provides a smooth and extended high frequency response.

Full-range input connection to the system is made via two 1/4” phone jacks and a four-pin Neutrik jack in parallel. A fourpin Neutrik switching jack is provided for bi-amping flexibility while maintaining superior signal integrity. The internal passive crossover features the Peaveyexclusive Sound Guard protection circuit for the tweeter and an advanced topology crossover with high-performance components to provide high power handling and reliability. 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 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 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 amplifier headroom available.

Harmonic distortion
Second and third harmonic distortions vs. frequency are plotted in figures 3 & 4 for two power levels. Ten percent (10%) of rated input power and either one percent (1%) of rated input power or 1 watt, whichever is greater. Distortion is read from the graph as the difference between the fundamental signal (frequency response) and the desired harmonic. As an example, a distortion curve that is down 40 dB from the fundamental is equivalent to 1% distortion.

Mounting
This unit is not designed for overhead suspension. The SA- 1 stand-mount adapter may be incorporated, and four large rubber feet are included on the bottom for floor use.
