The FLS115 is a subcardioid line array subwoofer module intended for permanent installation in a wide range of venues. It includes a single, high power 15 inch direct-radiating woofer in a compact enclosure. The FLS115’s rigging is designed to easily attach to the FL283 subcardioid line array module. The enclosure is shaped to accommodate up to 20 degrees of splay between adjacent enclosures, allowing for more sharply curved arrays than comparable line array subwoofers. Up to twelve modules may be suspended with a 10:1 design factor.
