The SP 2BX 2-Way Speaker System from Peavey is capable of 1,000-watts of program and 2,000-watts peak performance. It is comprised of the 15" Black Widow BWX SF series woofer with a Kevlar-impregnated cone. This driver is coupled to a Quadratic Throat Constant Directivity Waveguide to provide smooth, even response, low distortion, and high frequency dispersion. The 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, which provides a smooth and extended high frequency response.
The SP 2BX has a trapezoidal- shaped enclosure, which is designed to reduce the buildup of standing waves inside the enclosure to minimize mid-bass and mid-range coloration. The enclosure is constructed of a hardwood panel coated with Peavey's HammerHead UV stabilized polyurea finish for increased durability and ruggedness. A full-length, wrap-around perforated steel grille protects the front of the enclosure. A stand-mount adapter is incorporated to accommodate a speaker stand.
Full-range input connection to the system is made via two 1/4" phone jacks and one four-pin twist lock connector in parallel. A four-pin Neutrik switching jack is provided for bi-amping flexibility while maintaining superior signal integrity. The internal passive crossover features the Peavey's Sound Guard protection circuit for the tweeter and a 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.
