Description

The new SP 5 features the Peavey

Quadratic Throat Waveguide ™ and an enclosure made from Baltic birch plywood. The SP 5 is a twoway speaker system comprised of a high output 15” Scorpion ® Plus HO woofer with a Kevlar ® -impregnated cone and an Rx ™ 22 compression driver loaded onto the patented constant directivity waveguide.

The SP 5 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 plywood and covered with a durable black carpet. Use of the

Baltic birch plywood provides an enclosure that is 25% lighter than the previous SP 5XL. The enclosure corners are reinforced with metal corners, and a powder-coated, perforated metal grille covers the lower half of the system to protect the woofer from external damage.

A built-in SA-1 stand-mount adapter accommodates speaker stand use.

The low frequencies are supplied by a 15” Scorpion Plus HO woofer with a Kevlar-impregnated cone and a highly linear suspension.

The high frequencies are handled by a 2” Rx22 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 is aimed at the audience instead of over their heads. This helps reduce ceiling reflections, ensuring greater clarity and gain before feedback. The Rx22 driver features the Radialinear Planar

Phase Correction System (U.S.

Patent #6,064,745), which provides smoother and extended high frequency response.

SPECIFICATIONS SP ™ 5 features Sound Guard ™ III tweeter protection circuit and an advanced topology crossover with high performance components to provide high power handling and reliability.

Sound Guard, Peavey’s proprietary high frequency driver protection circuitry, provides long- and medium-term driver overload protection without impairing musical transients or dynamics when the system is used full range.

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

69 Hz to 17 kHz.

Despite its compact dimensions, this system can produce very high sound levels and handle 800 Watts program power, resulting in clean coverage with high articulation and long-term reliability.

Input connection to the system is made via two 1/4” phone jacks and a four-pin Neutrik in parallel.

Frequency Response

This measurement is useful in determining how accurately a given unit reproduces an input signal.

The frequency response of the

SP 5 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 5 combine to give a smooth frequency response from 69 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.

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.
