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.


To celebrate 25 years of great Danish loudspeaker design, DALI proudly introduces the 25th Anniversary Limited Edition of HELICON 400 MK2. Finished in a stunning high gloss real piano black, the cabinets are lacquered 7 times and polished after each coat for enhanced depth and sheen to rival the world’s finest pianos.

The Limited Edition loudspeakers prominently feature a golden logo badge on the front and a golden Limited Edition nameplate on the rear panel of each unique set of speakers.

DALI HELICON 400 MK2 25th Anniversary Limited Edition features a proprietary DALI Hybrid Tweeter Module, combining a ribbon and a low-mass soft dome, and two high performance 6½” mid/woofers with Class A magnet systems. Internally, the crossover incorporates select audiophile grade components in common with DALI’s state of the art EUPHONIA Series. The speaker is fitted with dual sets of high quality vice-grip screw terminals for bi-wiring/bi–amping. To maximize musical capabilities, all components are optimised for minimal electrical and mechanical loss.
