Stadium Series 3-Module Outdoor Line Array

The weather-resistant S-XL3-20 achieves an impressive 160˚ horizontal dispersion pattern. It excels in the most extreme environments, such as football and soccer fields, baseball stadiums, and amusement parks. The very broad dispersion reduces the quantity of enclosures needed to provide consistent coverage and minimize comb filtering.

Using three 8-inch, 800W cone drivers and three 1.4-inch exit-diameter horns in a tuned enclosure, the S-XL3-20 provides a symmetrical coverage pattern, ensuring minimal distortion and smooth, extended low-frequency response. It is available as a passive system.

Super Wide Dispersion and High Output Outdoors

All enclosures are manufactured using Baltic birch cross-laminated wood and finished with a polyurea coating (inside and out), with UV exterior outdoor protection and a fiberglass seal coating inside and out. The stainless steel fasteners will maintain their appearance, while a stainless steel, perforated grille, backed with a vinyl mesh, completes each system.
