HDN 80

Representing a formidable balance of compact design and blistering acoustic power, the HDN 80 is a top-tier high-frequency compression driver built for elite audio reproduction. This transducer is meticulously engineered to elevate the high-frequency response of professional 2-way passive loudspeakers and compact active line arrays. It shines exceptionally bright in applications demanding high fidelity in smaller form factors, making it an ideal candidate for touring front fills, premium stage monitoring, and sophisticated fixed venue installs where space is at a premium but high output is mandatory.

Do not let its compact footprint deceive you; the HDN 80 delivers intense acoustic output characterized by a stellar 109 dB sensitivity rating. It is rated for a rock-solid 80 watts of continuous AES power and effortlessly absorbs peaks with its 160-watt program power handling capability. This ensures that the driver provides ample dynamic headroom, easily cutting through heavy low-frequency stage energy to deliver staggering overall loudness. Live sound engineers can rely on this driver to maintain pristine clarity and completely avoid harsh harmonic distortion, even when pushed to extreme volumes during the climax of a show.

The internal architecture of the HDN 80 is driven by a precision-wound 2.5-inch (63.5mm) copper-clad aluminum voice coil, governed by an incredibly powerful yet lightweight neodymium magnet structure. This motor design ensures a remarkably fast transient attack and unparalleled control over diaphragm excursion. Sound waves are brilliantly funneled through a standard 1.4-inch throat exit, which, when paired with the appropriate waveguide, shapes the dispersion angle to provide wide, consistent, and phase-accurate coverage that blankets the audience area flawlessly.

Fidelity is paramount for the HDN 80, which accurately reproduces a vital frequency range spanning from 1 kHz all the way up to an airy 20 kHz. At the heart of this acoustic purity is an advanced PEEK (Polyetheretherketone) diaphragm, renowned in the pro audio world for its excellent internal damping and structural integrity. This results in a sonic character that audio technicians crave: remarkably transparent mids for hyper-realistic vocal reproduction and exceptionally sweet, crystal-clear highs that never sound brittle or harsh. The driver’s crossover efficiency allows for seamless integration into any bi-amplified or passive network.

When it comes to hardware and real-world value, the HDN 80 is a masterclass in road-worthy engineering. The incredibly low net weight of just 1.7 kg, combined with a shallow overall depth of 48mm and a 120mm diameter, makes it a dream for reducing the gravitational load on flown speaker arrays and portable polymer enclosures. It mounts securely to waveguides via standard 4 x M6 bolt-circle holes, ensuring a vibration-free mechanical bond. Available in standard 8 or 16-ohm nominal impedances, this exceptionally rugged transducer guarantees night-after-night reliability for the most grueling touring schedules
