Extron SM 28T 8" Two-Way Surface Mount Speakers with 70/100 V ...
The Extron SM 28T is a pair of high-performance two-way surface-mount speakers with integrated 70/100 V transformers, designed for distributed audio installations requiring powerful speech clarity and music reproduction in professional environments. Each speaker features an 8-inch (203 mm) polypropylene cone woofer and a 1-inch (25 mm) ferrofluid-cooled dome tweeter in a rugged, paintable black ABS enclosure with a low-profile, weather-resistant design. The speakers deliver a wide frequency response of 60 Hz to 20 kHz with 110° conical coverage, providing even sound distribution across large, open spaces such as auditoriums, gymnasiums, atriums, retail areas, conference centers, and hospitality environments.
The built-in 70/100 V transformer offers multiple power taps up to 64 W, plus an 8-ohm bypass for low-impedance systems, making the SM 28T compatible with Extron amplifiers or standard commercial audio setups. Included adjustable wall-mount brackets allow flexible horizontal or vertical orientation, while the paintable black enclosure and grille enable seamless aesthetic integration or custom color matching. Sold as a matched pair in black finish for consistent stereo or distributed mono coverage.
