The HELVIA DICO series column speakers were designed to bring together two key elements: acoustic performance and modern aesthetics. Each model uses 50×90mm full-range drivers with a slim, runway-shaped profile -equivalent to a standard 2.5″ transducer – paired with 1″ point-source tweeters. This setup works like a mini line array, minimizing unwanted reflections from floors and ceilings. The result is crystal-clear voice reproduction and enhanced overall definition across the full frequency range, from 120Hz up to 20kHz. The longer the array, the more extended the cylindrical sound wave it generates – keeping sound levels consistent even at greater listening distances compared to conventional point-source systems. When paired with a subwoofer system, the DICO speakers deliver deep, well-balanced lows for a smooth and immersive sound experience. Equipped with a line transformer and a 3-position selector, the DICO columns can easily connect to both constant-voltage amplifiers (70V/100V) and low-impedance systems. The protections on the connections and connection cables also make them waterproof and suitable for indoor and outdoor use, with an IP66 protection rating. Aesthetically, the slim and stylish profile blends seamlessly into architectural installations or modern minimalist environments. With lighter weight, compact size, and included wall-mount accessories, DICO column speakers are the perfect choice for conference rooms, worship venues, classrooms, auditoriums, and design-focused installations. Each column comes with a wall mounting bracket with both horizontal and vertical adjustment.
