HDN 100

The HDN 100 stands as a premier acoustic solution for audio professionals who demand exceptional high-frequency definition and deeply reliable performance. This advanced compression driver is perfectly tailored to act as the high-end beating heart for robust 2-way passive cabinets and precision-focused active line arrays. Whether tasked with driving the primary vocal range in a high-SPL touring system, outfitting a high-end fixed venue installation, or delivering critical feedback in stage monitoring setups, this driver consistently delivers uncompromising professional results.
Engineered to push serious volume without breaking a sweat, the HDN 100 boasts an incredibly efficient 110 dB sensitivity rating (1W/1m) for massive acoustic output. It confidently handles 100 watts of continuous AES power while accommodating aggressive transient spikes up to a 200-watt program threshold. This exceptional thermal capacity translates directly to vast dynamic headroom and breathtaking overall loudness. Audio technicians can push their systems to the absolute limit, knowing the HDN 100 will maintain its structural and sonic integrity, keeping the highest frequencies crystal clear at extreme sound pressure levels.
At the core of its internal acoustics lies a meticulously crafted 3-inch (74.5mm) copper-clad aluminum voice coil, suspended within a high-flux neodymium magnet structure. This powerful motor assembly ensures rapid transient response and intense magnetic force, driving the acoustic output through a highly versatile 1.4-inch throat exit. When coupled with a premium professional horn flare, this throat geometry facilitates optimal dispersion characteristics, guaranteeing that every seat in the house experiences consistent, phase-accurate coverage without dead zones or high-frequency beaming.
Sonically, the HDN 100 operates flawlessly across a wide frequency range of 900 Hz to 20 kHz, ensuring that no delicate audio nuance is lost in the mix. The secret to its acoustic purity is a highly specialized hybrid diaphragm constructed from a precise blend of titanium and PEEK (Polyetheretherketone). This unique material synergy yields a remarkable sonic character: the titanium ensures razor-sharp, transparent upper mids for ultimate vocal intelligibility, while the PEEK polymer tames aggressive resonances to deliver smooth, crystal-clear highs. Its crossover efficiency ensures a highly phase-coherent handoff to the low-frequency transducers.
Designed for the harsh realities of live production, the physical hardware of the HDN 100 is engineered for maximum real-world value and road-worthiness. The driver is astonishingly compact, measuring just 135mm in overall diameter and 62mm in depth, with a featherweight 2.7 kg profile that drastically reduces the rigging weight of large line arrays. System integration is securely handled by 4 x M6 bolt-circle mounting holes, and it is available in versatile 8 or 16-ohm nominal impedances to suit varying amplifier topologies. It is a rugged, deeply reliable workhorse built to endure years of demanding professional use.
