Faith in Power. CODA in Sound. Clarity in Every Detail.

Built for professionals who demand uncompromising performance, this HF-D405 TRIO compression driver redefines what precision audio can deliver. At its core lies a robust 4-inch (101.6 mm) voice coil engineered to handle extreme thermal stress while maintaining long-term stability. With up to 400W RMS and 2000W peak power handling, it is designed to perform under pressure without distortion or fatigue.

Faith begins in its construction—every component is selected for reliability, from the high-strength diaphragm options in titanium or phenolic to the reinforced magnetic structure. This is not just a speaker driver; it is a commitment to consistent performance in the most demanding professional environments.

CODA arrives in the final output—when power, projection, and dynamics converge into a controlled yet explosive soundstage. Whether installed in large PA systems, touring rigs, or fixed installations, the HF-D405 TRIO delivers impact that closes every performance with authority.

Clarity defines its signature. High-frequency response remains smooth, detailed, and articulate even at high SPL levels, ensuring vocals and instruments retain natural presence without harshness.

Engineered for those who refuse compromise, this is sound built on Faith, defined by CODA, and perfected in Clarity.
