Product Overview
The Biamp Desono DS8 is an 8-inch two-way coaxial surface-mount loudspeaker, sold as a pair and supplied in black. It is a low-profile, compact enclosure with dynamic sound quality and excellent intelligibility for larger installations. The built-in autoformer allows full loudspeaker output on low-impedance or 70V/100V distribution lines. It is ideally suited to a wide variety of speech and music applications.
Product Description
For larger installations, the DS8 provides higher sound pressure levels, higher sensitivity, and greater bass extension, and easily outperforms competitive 10-inch format loudspeakers. The cabinet uses thick-wall, internally reinforced high-impact ABS construction with rounded surfaces to reduce acoustic resonances. It features zinc-rich epoxy dual-layer powder-coated grilles and mounting brackets, stainless steel hardware, and an included IP56 wiring cover, with weather-resistant capability. The DS8 shares the same components and voicing as the Distributed Design ceiling loudspeaker family and includes the Infin-A-Ball low-profile mounting bracket. It is offered in black.
Key Features
- Two-Way Coaxial Design — An 8-inch LF cone and 1.25-inch exit HF compression driver deliver high output and intelligibility.
- Built-In Autoformer — A front-accessible power tap switch selects 8-ohm or 70V/100V operation.
- Infin-A-Ball Mounting — The included Infin-A-Ball low-profile bracket provides hidden internal wiring.
- Weather-Resistant Construction — Treated drivers, two-layer powder-coated grilles, and protected wiring ingress suit demanding environments.
- Paintable Enclosure — The high-impact ABS enclosure is paintable and resists resonances.
Typical Applications
- Commercial meeting space
- Multi-purpose room
- House of worship
