The 1508 and 1208 driver series represent a new level of power and performance for Black Widow loudspeakers. Power handling is increased by 40% over other comparable models, along with reduced distortion and higher overall sound quality.The series includes 12" and 15" models in both 4 and 8 ohm impedances.DESIGNThe BWX series uses a new cone that is a variation on the existing Kevlar impregnated cones used on all Black Widows. The new cone is stronger and tougher, highly water resistant, and has a specially designed surround - a deep roll accordion design on the 15", and an innovative asymmetrical-M style on the 12" that improves mid range clarity. The dust cap is also made of the same extremely strong material.APPLICATIONSThe 1508 and 1208 drivers are excellent choices for a wide range of sound reinforcement, high level playback, subwoofer, and monitor applications. The 15" drivers can work with crossover points as high as 2.0 kHz but work best below 1.5 kHz. The 12" drivers are usable to 3.5 kHz but perform best below 2.5 kHz.ENCLOSURESTo assist with the growing interest in home built enclosure designs, Peavey provides complete parameter data on these drivers, as well as several recommended enclosures for each model. This information and much more can be found at www.peavey.com.The strength of the completed enclosure has a great effect on the bass performance of the finished system. Box panels that aren t stiff enough will vibrate, canceling bass produced by the woofer and creating undesired sounds of their own. If your box vibrates or you don t think the box panels are stiff enough, add more bracing.
