The Selenium by JBL 15PW7 is a professional 15" woofer used to meet a variety of PA needs for small and medium-sized rooms, with excellent performance in the mid and low frequency ranges. Its great efficiency in sound reproduction is due to the excellent combination of the different components. The light cone manufactured with long fibre pulp together with a surround of impregnated fabric give the array great stability, high yield and low distortion. The voice coil is made of high temperature wire. The epoxy painted reinforced steel frame provides the array with high mechanical resistance. The use of highly resistant adhesives guarantees optimal cohesion and durability of components.
