The SA-12 is a 2-way full range system in a trapezoidal, computer optimized enclosure. Loud speaker complement consists of an 12" LF woofer in a ported sub-enclosure, and a single 1.5"compression driver mounted on a 80o×50o horn. A factory optimized internal crossover is installed to ensure balanced output between the HF and LF components. The enclosure is constructed of durable 13-ply void-free birch laminate, dadoed for strength and durability. Integrated eyebolt receptacles are located on the top of the system to facilitate a vertical installation. Perforated steel is employed for frontal protection of the loud speaker complement.
