The Outline VEGAS 15 is a professional 2-way passive coaxial enclosure featuring a 15″ neodymium low-frequency driver and 3″ high-frequency diaphragm, engineered for exceptional sonic effectiveness and ease of use in venues ranging from 10 to 30 meters of throw distance. This point-source loudspeaker features true coaxial architecture that provides exceptional directivity control with an 80° x 60° dispersion pattern, ensuring consistent sound coverage across the listening area for live events and professional installations. Furthermore, the coaxial configuration delivers precise time-alignment in both mono and bi-amped operations, ensuring remarkable sonic clarity. Built from certified Baltic birch plywood with dovetail-joint construction and structural braces, this enclosure delivers maximum stiffness and durability, while the cabinet features a high-protection polyurea coating graded to Outline’s proprietary Solar Gris tone. Additionally, the weave-patterned pressed-steel front grille includes a rotatable “always-ortho” logo shield, combining professional aesthetics with practical functionality. The asymmetrical cabinet design features different discrete angles for use as a wedge monitor, offering 30° and 55° positioning options, while supporting both Mono Amp and Bi Amp operation modes for flexible system configuration. Moreover, the VEGAS 15 achieves impressive maximum output levels of 136.7 dBZpk while maintaining excellent frequency response from 45 Hz to 19.5 kHz. Equipped with dual Neutrik Speakon NL4 connectors in parallel, the VEGAS 15 ensures reliable professional connections, and features IP 54 rating for weather resistance during outdoor applications. The enclosure includes multiple mounting points (6 x M8, 4 x M6) and two integrated handles on the rear for easy transport and installation flexibility.
