About the SUB Air
The Focal Sub Air is a compact, flat bass-reflex powered subwoofer featuring wireless connectivity via an included transmitter, allowing placement flexibility up to 49 feet (15m) range. Its shallow 6.3-inch depth enables wall-mounting without sacrificing floor space, and it delivers deep, punchy bass down to 35Hz (-6dB) to complement 5.1 systems. Key features include auto on/standby, variable crossover (50-200Hz), phase adjustment (0-180°), and high-gloss black finish. The 8-inch cellulose pulp cone woofer in a front-firing ported enclosure pairs with a built-in BASH amplifier for dynamic low-end performance. Easy setup with synchronization button and LFE/Left-Right RCA inputs on the transmitter.
