With a horizontal coverage very wide, next to the 180 °, the speaker Control HST's JBL Professionall, whose products marketed Earpro in the Iberian market, used for this wall on which it is mounted, whether for interior applications or in outside, which can be combined with systems of notices.

"Control HST not only solves inherent reflections arising from mounting on wall, they, in fact, makes the wall part of the operation of the speaker - explains Rick Kamlet, senior manager commercial sound JBL. A single speaker Control HST can offer wall-to-wall coverage, which can reduce the number of enclosures needed to cover a space, thus reducing the total sound system costs".

System incorporates the HST (Hemispherical Soundfield Technology) technology from JBL, of recent development, to offers a wide coverage and eliminate the primary reflection on wall, which normally cause an inconsistent sound when the speakers are they are mounted on wall. This is due, to be Speaker of the own speaker some distance from the wall, low frequencies and stockings tend naturally to wrap the speaker, causing reflections on the wall that are mixed with the original sound.

Reflections will be in phase with the signal coming from the transducers and others will be out phase, which produces reinforcements, cancellations, peaks and valleys in the frequency response of the speaker, something that is avoided with this technology.

Using a woofer facing the wall, two tweeters separated horizontally, a fitting that separates the speaker from the wall to the required distance and accommodation which offers adequate cargo and dispersion of sound, Control HST reduces substantially these inconsistencies to deliver a frequency response flatter and a character sound more balanced throughout the room.

Además, el material CMMD ofrece resistencia a la humedad.

Por su parte, los tweeters CMMD duales de 1″ de la caja acústica cuentan con imán de neodimio, exterior de poliuretano y refrigeración de ferrofluído para ofrecer altos niveles de salida, con baja distorsión. Control HST es capaz de manejar hasta 100 watios y está equipado con un conector phoenix de bloqueo (desmontable) de 4 pines que incluye terminales de salida directa loop-through para la conexión en paralelo de otra caja acústica.

Esta caja acústica debe instalarse utilizando este herraje con el fin de asegurar el espaciado adecuado desde la pared, así como un funcionamiento acústico correcto, y no se debe montar en esquinas ni sobre soportes verticales.

El alojamiento de ABS reforzado con fibra de vidrio, la rejilla de aluminio pintada y los transductores resistentes a la intemperie aseguran un funcionamiento fiable, incluso bajo condiciones medioambientales agresivas.
