SPEAKER SA1521 Active Speaker System SA1521 (continued from page 1)  The SA1521 cabinet is constructed using both multi- layered plywood and pressure injected structural resin. The combination provides a robust enclosure with useful ergonomic features. There are three-part cast aluminum handles on each side of the enclosure placed at the speaker's center of gravity for easy carrying and setup. Handles are also located on the top and bottom of the cabinet for easy movement and relocation. A built-in pole-mount cup is provided on the bottom, and a full-size, oval punched, weather-resistant steel grille protects the front of the cabinet.
