A truly versatile compact full-range driver perfectly suited for tight fitting pro audio line array and column array applications. An 8.3 oz ferrite magnet used in conjunction with an internal neodymium bucking magnet increases the sensitivity and extends the response out to 20kHz. The highly pressed cone sandwiches paper with a layer of water-resistant polypropylene for increased stiffness and lower distortion.
