 The SA1521 cabinet is constructed using both multi-
layered plywood and pressure injected structural resin. The
combination provides a robust enclosure with useful ergo-
nomic 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 locat-
ed 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.
