hd PL32i

The hd PL32i PowerLine Stick is equipped with 32 3″ broadband speakers. The elegant rounded loudspeaker housing made of aluminum allows a particularly high packing density of the loudspeakers. Therefore, the drivers couple to a 5° vertically opening wavefront 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 large throw range of up to 38 m and horizontal coverage of 80° ensures efficient sound solutions with only a few speakers. 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 PL 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 hd PL-Series 1-way design shines: full-range speakers that cover the fundamental range up to the harmonic, the linear array with its LineArray benefits, and the coherence of the sound wave, with no “phasing” and group delay a listening experience in a class of its own.

The continuous U-slot for M6 square nuts on the back allows any mounting of wall brackets. Internal clamping connections ensure a tool-free and quick connection of the loudspeaker. For optimum adaptation to the room architecture, the loudspeaker can be customized in all RAL colors and special lengths.
