The 63SA-8HO.8 has a small width print with an 8-inch depth and is best suited for in-ceiling applications. The Small Aperture in-ceiling/in-wall speakers have a very small 3-inch round or 3x3-inch square sound aperture yet pack in a full 3-way speaker system for deep bass and wide frequency response. A seamless edge detail keeps SA speakers looking smart and modern yet discrete. The 63SA-8HO.8’s aircraft-grade aluminum enclosure was designed with a slender 8-inch width for newer, more constricted ceiling construction. This system includes a mini PowerPipe 6.5-inch subwoofer, 2-inch midrange, and 3/4-inch dome tweeter for wide 38Hz to 22kHz response. Having a real subwoofer also allows the system to play at higher output levels. Deep bass and high SPL from such a small, barely visible opening are the key objectives of the SA Series. Premium components and modular design provide long life and easy service, while an internal protection circuit offers the utmost reliability. The SA series is designed to also accept industry standard lighting trim kits to allow integration with similar styled lighting products.
