DALI's unique hybrid tweeter module for sparkling, extended high frequencies with remarkable resolution.


DALI's crossovers are designed for smooth seamless sound as if everything you hear originated from a single ideal drive unit.


Our low-loss drivers uses a mix of low-mass paper cones with wood fibre reinforcement. The embedded wood fibres give the surface an uneven structure, which dramatically minimizes the resonance of the surface. This creates the best possible reproduction of every detail in the audio signal.


Engineered by DALI for ultra low contact resistance, durability and mechanically sturdy construction. High quality gold-plated binding posts.
