Advanced Boundary Free Surround Technology

The Hertz ML 1800.3 LEGEND features the innovative Boundary Free Surround design, developed to maximize the effective cone area compared to conventional speakers of the same diameter.

This technology allows the cone to move a larger volume of air, increasing acoustic pressure, improving efficiency, and delivering deeper, more powerful midbass performance without compromising accuracy.

Exceptional Power Handling & Control

The 50 mm (2″) CCAW double-layer voice coil mounted on a Polyamide former provides excellent thermal stability and outstanding power handling. This advanced construction reduces power compression and maintains consistent performance during demanding musical passages.

The optimized neodymium magnet system, developed through FEA simulations, delivers high efficiency, fast transient response, and precise control at high output levels.

Premium Materials for Superior Sound

The ML 1800.3 LEGEND uses a specially developed pressed-pulp cone reinforced with cotton fibers, offering the ideal balance between stiffness and lightweight construction.

Combined with the V-Cone® geometry, the result is:

• Accurate midbass response
• Improved dispersion
• Reduced distortion
• Natural and detailed musical reproduction
