PA-215 15” TWO-WAY The B-52 PA-215 has excellent high-output and full bandwidth coverage from an extremely compact full-range cabinet. Components include a B-52 15-200 loudspeaker with a cast-aluminum frame, a precision-wound 4” polyamide voice coil and a 1” titanium diaphragm compression driver. The PA-215 is designed for those seeking a maximum output system that is modest in both size and weight. * Made in the U.S.A. * High-temperature polyamide voice coils * Cast-aluminum frames * Titanium diaphragm compression drivers * 13-ply void-free Baltic birch construction * Black or white scratch resistant acrylic * textured paint * Internal flying hardware (3/8"-16 TPI) * Internal acoustic dampening * Enhanced-grip B-52 handles * Pole-mount adaptors * Dual Neutrik NL4 Speakon connectors REAR PORTING USING THE AEROPORTS All B-52 Medium and Large / Concert Systems are rear ported using Aeroports. Rear porting results in a smoother sound wave since the inherent problems associated with the interaction of loudspeakers and ports are virtually eliminated. This design smoothes the air flowing in and out of the cabinet, reducing port turbulence and exit noise inherent to conventional porting. The Aeroport increases linearity, lowers distortion, reduces 5th-order harmonic distortion and provides an output increase as high as 2-3 dB. 2” EXIT TITANIUM COMPRESSION DRIVER The Selenium D3300ti compression driver features a 2" exit pure titanium diaphragm designed with Impregnated Polymer Fiber surround for high sensitivity, low distortion and a smooth extended frequency response. An optimized aluminum injected phase plug avoids phase cancellation problems. High flux density magnetic assembly with copper shorting ring lowers distortion and reduces the voice coil self-inductance. The compression driver's base and cover are injected aluminum assuring high mechanical resistance. B-52’s enhanced-grip metal handles are the ultimate solution for carrying your B-52 loudspeakers. Constructed of bullet-proof stamped steel with a pressure-sensitive rubber backed grip, these handles are specially designed to fit in the palm of your hand. All Architectural Series folded horn subwoofer cabinets feature 13-ply Baltic birch construction, scratch resistant black or white paint finish and a LIFETIME construction warranty. As always, the very impressive B-52 standard warranty: Lifetime warranty on cabinet construction Lifetime warranty on high-frequency devices Five-year warranty on loudspeakers Two-year warranty on amplifiers |
