The hd ML32 LineArray Stick is equipped with 32 2″ broadband speakers. The elegant round speaker housing made of aluminum allows a particularly high packing density of the speakers. Therefore, the 32 drivers couple to a wavefront that opens at 8° vertically, so that the system operates on the principle of the cylindrical wave. The result is a consistent sound pressure level and nuanced sound from the first to the last row. The precise horizontal beam angle of 100° allows a direct alignment of the sound to the audience without unwanted reflections of walls or windows. This leads to more direct sound, offers a higher speech intelligibility and a high feedback safety in acoustically problematic rooms, with lower basic volume. Therefore, the hd ML column speakers are ideal for voice and music transmission in halls and churches.

In order to transmit a sound event from the fundamental to the overtones, conventional loudspeakers use two or three different types of transducers. This results in incoherence not only in the crossover areas, but also in the important mid-frequency-range due to the different decay times and the different diaphragm mass of the transducers types in a different “response characteristic”. Especially in the reproduction of instruments or speech in which the fundamental range is covered by the one type of transducer and the overtone range by the other type of transducer, the sound is distorted. This is where the 1-way design of the hd ML-Series shines: The full-range speakers that cover the fundamental range up to the overtone range, the arrangement as a line with its LineArray advantages and the coherence of the sound wave, without “phasing” and group delay make the playback to a listening experience in a class of its own. The continuous metal rail for M6 square nuts on the back allows any mounting of wall brackets or a tiltable tripod adapter. On the bottom there is a built-in 35mm flange. A high-quality powder coating of the aluminum profile and a finely structured design grid with backed acoustic foam ensures an unobtrusive integration into any room architecture.
