The SP 4 features the Peavey Quadratic Throat Waveguide with an RX™ 22CT compression driver loaded onto the constant directivity waveguide. The SP 4 is a quasi-three way speaker system comprised of two of the 15” Black Widow® BWX series woofer, now with a long throw voice coil.

The SP 4 has a trapezoidal-shaped enclosure, which reduces the buildup of standing waves inside the enclosure to minimize mid-bass and mid-range coloration. The enclosure is constructed of plywood augmented with internal braces, Coated with a textured black polyurethane finish. A full-length, wrap-around perforated steel grille protects the front of the enclosure. Multiple fly points are provided to allow overhead rigging.

The quasi-three way system consists of the following driver components: two 15” Black Widow® BWX series woofer with a long throw voice coil. The woofers are each capable of over 500 Watts of continuous power handling (AES Std 2-1984). The high frequencies are handled by a 2” RX™22CT titanium diaphragm compression driver. This excellent 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.

Full-range input connection to the system is made via two 1/4” phone jacks and one four-pin twist lock connector in parallel. Bi-amp input is via a swappable plug and headers inside the input cup. The internal passive crossover features the Peavey-exclusive 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 bi-amped.

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 2000 watts program power, resulting in high articulation and long-term reliability.
