Peavey SP 4BX

The SP 4BX is a quasi three-way speaker system comprised of two 15" Black Widow BWX SF series woofer with high strength cones, and an RX 22CT compression driver loaded onto a constant directivity Quadratic Throat Waveguide.

The SP 4BX has a trapezoidal-shaped enclosure, which reduces the buildup of standing waves inside the enclosure to minimize mid-bass and midrange coloration. The enclosure is constructed of a hardwood panel coated with a polyurea finish for increased durability and ruggedness. Casters are incorporated to improve portability. A full-length, wrap-around perforated steel grille protects the front of the enclosure.
