Hertz ML 280.3 Legend
Upgrade Your Vehicle With Confidence. This Is Built to Fit, Perform, and Last
Hertz ML 280.3 Legend | Mille Legend Series 1.5" Tweeters
The Hertz ML 280.3 Legend is the flagship tweeter of the Hertz lineup, representing the absolute pinnacle of their "Sound Experience." Engineered to surpass its predecessor—a long-standing industry reference—this 35 mm (1.38 in) tweeter is designed for ultra-high-end active systems. By utilizing sophisticated FEA (Finite Element Analysis) simulations and high-grade materials like Tetolon and Neodymium, the ML 280.3 delivers a level of transparency and natural detail that brings a "live" performance directly to your dashboard.
Product Highlights
Oversized Tetolon® Dome: The 35 mm (1.38 in) housing features a specialized Tetolon fiber dome with optimized geometry. This material provides the perfect balance of low mass and high damping, ensuring the high frequencies are silky smooth and incredibly detailed without any of the "ringing" common in metal domes.
Enhanced Rear Acoustic Chamber: Hertz designers completely redesigned the rear chamber, achieving a 50% increase in volume over previous models. This larger space effectively lowers the resonance frequency to 900 Hz, allowing the tweeter to be crossed over much lower to improve the soundstage and vocal "presence" on the dash.
Flagship Motor Structure: The motor utilizes a high-density Neodymium magnet and a CNC-machined aluminum housing. This structure is mechanically inert, meaning it doesn't vibrate or add its own "color" to the sound, ensuring you hear only the pure recording as intended.
Pure Copper Shorting Ring: To further refine the high-end response, an extremely pure copper ring is integrated into the magnetic circuit. This reduces impedance modulation and harmonic distortion, allowing the speaker to extend clearly up to 28 kHz.
Key Features
Reference-Grade Directivity: The faceplate geometry has been entirely reviewed to improve off-axis frequency response. This ensures that even when mounted in factory A-pillar or dashboard locations, the imaging remains sharp and the high-end remains linear.
Precision Voice Coil: The 28 mm (1.1 in) voice coil is wound with premium materials to ensure high power handling and thermal stability, allowing the tweeter to maintain its clarity even during demanding, high-volume listening sessions.
Machined Aluminum Construction: The elegant, die-cast aluminum body not only looks premium but also acts as a heat sink, providing superior thermal management and structural rigidity compared to plastic-housed tweeters.
Mille Legend Pedigree: As part of the Legend series, every component of the ML 280.3 is tested to meet the highest audiophile standards, making it the definitive choice for a world-class front stage.
