Harmonic Design PL16 600 W passive PowerLine stick, 16 x 3", 80° x 10° dispersion, 4 ohm, speakON connector
FEATURES
Column speaker equipped with 16 x 3" full-range loudspeakers housed in an elegant rounded aluminum cabinet. The drivers couple to create a (quasi) cylindrical wave front with a 10° vertical opening; the result is a constant sound pressure level and an almost uniform sound reproduction from the first to the last row.
The long throw (up to 25 m) and 80° horizontal coverage allow for high efficiency with few loudspeakers. This results in a more direct sound, offers greater speech intelligibility, and high feedback rejection in acoustically challenging rooms.
Therefore, the hd PL series column speakers are ideal for voice and music reproduction in halls, clubs, and churches. Compared to the hd ML24, the hd PL16 stands out with a lower overall height at the same weight, which facilitates use in locations with low ceiling height and allows for easy transport by car.
Thanks to the increased directivity of the 3" drivers, the 80° horizontal opening angle means that sound energy is conveyed even more, thus allowing for a longer throw. With a larger diaphragm surface than the hd ML24, music and speech reproduction in the mid-low range of the hd PL16 is even more powerful, and a higher sound pressure can be achieved.
In fixed installations, the use of a subwoofer for speech reproduction can be avoided thanks to the full-range capability of the system.
To reproduce a sound program from the fundamental to the harmonics, conventional loudspeakers use two or three different types of transducers. This results in inconsistency not only near the crossover frequencies, but also in the important mid-frequency range due to different decay times and different diaphragm masses of different transducers. Especially in reproduction where the low range is covered by one type of transducer and the high range by another, the sound can be distorted. This is where the 1-way design of the PL hd series comes out on top: full-range loudspeakers covering the fundamental range up to the harmonic, the advantages of the Line Array (cylindrical wave) and the coherence of the sound wave, without "phasing" and group delay: a unique listening experience.
The continuous metal guide for M6 cage nuts on the back allows any mounting of wall brackets or a tiltable tripod adapter. A high-quality powder coating in aluminum and acoustic foam complete the features of the PL series.
For safe transport, Harmonic Design offers a customized nylon case with full zipper, handle, and shoulder strap.
