The SW215 is a very powerful band pass rear horn-loaded subwoofer designed for use in large nightclub applications, although it is also ideally suited to concert touring and festivals. A high-velocity band pass horn-loading technique, gives precise cone control, resulting in a deep and fast bass response at high power levels, with a very high sensitivity. The response given with this subwoofer is very deep, starting at 36 Hz, but at the same time it delivers tremendous punch due its fast transient response. The enclosure has been made with the latest techniques ensuring a perfect and rigid construction. Weatherized finish is provided, as the cabinet is coated with rugged Durawound texture finish and protected with specially treated grills.
