B52 PA-15X Two-Way 15" Large Concert Speakers |
 15” TWO-WAY The B-52 PA-15X provides high acoustic output with smooth mids and accurate highs that are not fatiguing to the ear. The PA-15X is ideally mated with a B-52 Architectural subwoofer for a high-power, full-fidelity system. The Seleniumtm 2” exit compression driver is coupled to a large format horn for wide dispersion, while the B-52 15-200 4" voice coiled loudspeaker delivers punchy low end. * Made in the U.S.A. * 4” high-temperature polyamide * voice coils * Cast-aluminum frames & vented * magnet assemblies * Seleniumtm 2” exit titanium * compression drivers * Selectable full-range/bi-amp mode switch * 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 * Dual Neutriktm 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. |
