RCF HF64 Horn

High-Frequency Horn Designed for Focused Sound Dispersion

The RCF HF64 is a professional-grade constant directivity horn built to deliver controlled high-frequency performance in demanding loudspeaker systems. With its 60° x 40° coverage pattern and 1"/1.4" throat adaptor, this horn is ideal for applications requiring sharp directional control and even sound coverage across the listening area. Whether you're building custom speaker arrays or replacing components in an existing PA system, the HF64 provides precision and reliability in one rugged package.

Ideal for Compact and High-Powered Compression Drivers

Designed for use with neodymium compression drivers, the HF64 is optimized to handle high-output demands while maintaining clarity and low distortion. Its thick cast aluminum body helps dissipate heat efficiently—crucial when paired with high-powered drivers—ensuring consistent performance over long sessions. This makes it a great fit for touring systems, fixed installs, and any setup requiring reliability at high sound pressure levels.

Constant Directivity Ensures Even Sound Coverage

The HF64 provides a controlled 60-degree horizontal by 40-degree vertical dispersion, making it ideal for focused coverage in reverberant or acoustically challenging spaces. Whether mounted in a large-format speaker cabinet or integrated into an array, it maintains uniform directivity and frequency response from the center to the edges of the horn’s throw, reducing hot spots and drop-offs.

Supports Extended Frequency Loading Down to 500 Hz

Unlike many horns that begin to taper off above 1 kHz, the HF64 offers acoustic loading as low as 500 Hz, helping to bridge the gap between mid and high-frequency components. This extended bandwidth makes it a versatile choice for crossover designs and multi-way loudspeaker systems that demand better phase alignment and cohesion across the spectrum.

Heavy-Duty Construction for Touring and Installation Rigs

The HF64 is built with a solid aluminum structure that adds durability without excessive weight. It’s designed to perform in both road and fixed-install environments. Its robust body also minimizes resonance, preserving the integrity of the driver’s output. The throat adaptor accommodates both 1" and 1.4" exit compression drivers, allowing compatibility with a wide range of industry-standard components.
