B-52 PA315

PA-315
15" THREE-WAY
The B52 PA-315 produces a remarkable full-range response with deep bass, smooth mids and pristine highs. It is ideal for venues where wide coverage and extremely high-output is required. The PA-315 utilizes a B-52 15-120 loudspeaker, an 8" midrange speaker housed in a dampened and sealed sub-enclosure and a 1" titanium diaphragm compression driver, mounted on a wave-guide horn.

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
