EAW CIS300 Ceiling Speaker (White)

Compact Ceiling Speaker for High-Fidelity Distributed Audio
The EAW CIS300 White is a compact two-way flush-mount ceiling speaker designed for fixed installations requiring wide coverage and detailed sound reproduction. Built for commercial and institutional settings, this speaker integrates a 4-inch low-frequency driver with a waveguide-loaded neodymium high-frequency transducer to provide controlled dispersion and consistent response across the listening area. Ideal for paging, background music, and AV system integration, the CIS300 combines acoustic performance with architectural discretion.

Advanced Waveguide Design Improves Sound Coverage
Unlike standard coaxial ceiling speakers, the CIS300 features a high-frequency waveguide adapted from EAW’s studio monitor technology. This design provides improved pattern control and a more even frequency response across the coverage area, reducing hot spots and dead zones in the room. Whether you're outfitting a boardroom, hotel lobby, courtroom, or classroom, the CIS300 delivers clarity and consistency not typically found in ceiling speakers at this size and price point.

Preassembled Steel Backcan Streamlines Installation
The CIS300 arrives fully assembled with a sealed, zinc-coated steel backcan and cam-style mounting clamps for rapid, tool-free installation into drop-tile or drywall ceilings. The included steel C-ring and T-bar support channels distribute clamping pressure and provide additional stability in standard ceiling grid installations. A hinged metal cover conceals the Euroblock input connector, ensuring clean wiring while offering easy access for connection and service.

Selectable 70/100V Transformer and 16-Ohm Operation
This ceiling speaker includes a built-in 30-watt transformer with a front-mounted recessed rotary switch for selecting 70V or 100V operation with 30, 15, 7.5, or 3.7 watt taps. A second switch enables 16-ohm bypass mode for use with low-impedance amplifiers in distributed sound systems or localized zones. Another selectable switch engages a 150 Hz high-pass filter, providing greater system control when used in multi-speaker or subwoofer-supported setups.

Architectural Finishes and Paintable Grille Options
A protective paper shield is preinstalled over the speaker’s face, keeping the drivers safe during ceiling mounting and serving as a paint mask for custom finishes. Once installation and tap settings are complete, the included powder-coated perforated steel grille snaps into place for a clean, professional appearance that blends into any interior design. This makes the CIS300 ideal for visually sensitive environments such as conference rooms, hotels, and places of worship.

Certified for Plenum Use and Safety-Compliant
The EAW CIS300 is fully certified to UL 1480 and UL 2043 standards, ensuring compliance with regulations for plenum-rated ceiling spaces and fire signaling applications. It is also UL/cUL/CE listed, making it suitable for a wide range of commercial AV installations requiring adherence to safety codes. A welded tab is included for seismic restraint compliance, further enhancing its reliability in fixed installations.

Reliable Performance Backed by a Five-Year Warranty
Each CIS300 is factory tested and backed by a five-year warranty, offering long-term peace of mind for system designers, integrators, and facility managers. With robust construction, flexible mounting, and clean acoustic performance, this ceiling speaker is a dependable choice for distributed audio systems in professional environments.
