Desono EX-S8 | 8-Inch Surface Mount Loudspeaker for Indoor and Outdoor Applications
The Desono™ EX-S8 surface mount loudspeaker offers a powerful combination of premium audio performance and refined aesthetics, making it ideal for a wide range of indoor and outdoor distributed sound systems. Part of the versatile EX Series lineup, the EX-S8 is a two-way, 8-inch loudspeaker engineered for high intelligibility, extended bandwidth, and consistent 105° x 105° coverage.
Featuring coaxially mounted HF and LF drivers, the EX-S8 delivers exceptional clarity and projection, making it an ideal choice for fill or distributed applications where enhanced voice reproduction, greater output, and deeper bass are required. Whether used in hospitality venues, corporate facilities, retail spaces, or educational institutions, the EX-S8 ensures pristine, balanced sound throughout the listening area.
Installation is quick and secure with Biamp’s patented Click Mount™ brackets, offering two mounting options: a pan-tilt bracket with indexed aiming for flexible vertical or horizontal installation, and a U-bracket for low-profile or outdoor use. Both options feature tamper- and theft-resistant designs and include the Click Plug with integrated weather-resistant gland nut.
With a selectable 70 V/100 V transformer and low-impedance input, the EX-S8 provides flexible integration with new or existing systems. Certified for commercial and life-safety applications, it meets UL 1480A, EN54-24, ISO 7240-24, and other key international standards.
