Desono D4 4.5-Inch Ceiling Loudspeaker (White / Pair)

Designed for Wide Dispersion in Compact Spaces
The Desono D4 ceiling loudspeaker offers exceptional audio clarity and a wide coverage pattern, making it ideal for environments where even sound distribution is critical. Sold as a pair, each speaker is a compact 4.5-inch coaxial loudspeaker that delivers professional-grade performance in commercial and public installations. Despite its smaller size, the D4 outperforms larger models with its advanced dispersion and true coaxial design.

True Coaxial Compression Driver for Clearer Highs
At the heart of the D4 is a high-performance compression driver concentrically mounted within the low-frequency driver’s structure. This design, paired with a specially tapered Tru-Phase™ waveguide, ensures consistent sound dispersion up to 16 kHz. The concentric alignment eliminates phase inconsistencies and high-frequency narrowing often found in offset driver designs, resulting in smooth and balanced sound coverage.

Optimized for Consistent Audio Performance
Each unit features a robust magnetic structure and efficient voice coils that allow higher output with more headroom. This translates into cleaner sound at higher volumes and reliable performance in demanding audio environments. The D4 is designed to deliver impressive clarity for both speech and music in a wide range of ceiling-mounted applications.

Flexible Installation with Built-In Transformer
Every D4 includes integrated hardware for fast, secure mounting and a built-in autoformer for both 70V/100V distributed audio systems and standard 8-ohm operation. This versatility simplifies system design and installation, allowing integration into new or existing audio infrastructures with minimal effort.

Certified and Code-Compliant for Safety and Reliability
The D4 loudspeaker is ETL listed and tested for compliance with UL1480, UL2043, and CSA60065 standards, ensuring suitability for use in plenum spaces and other code-regulated environments. Whether for schools, offices, hospitality, or retail, it meets the highest safety benchmarks required for commercial sound systems.

Amplifier Compatibility for Enhanced Control
For optimal performance, the D4 is recommended for use with the Community ALC404D Amplified Loudspeaker Controller. However, it’s also fully compatible with higher-powered ALC models, offering flexibility for larger system designs and future expansion.

Aesthetics and Performance in Harmony
Blending subtle design with top-tier audio performance, the Desono D4 integrates cleanly into any architectural setting while providing consistent full-range sound. It’s a smart solution for integrators who need excellent fidelity and even coverage without compromising the visual space.
