Control HTC: JBL Professional loudspeaker with wide indoor and outdoor coverage

The new Control HST acoustic enclosure from JBL Professional incorporates Hemispherical Soundfield Technology to offer wide horizontal coverage in both indoor and outdoor installations.

With very wide horizontal coverage, close to 180º, the Control HST speaker JBL Professional, whose products it sells Earpro in the Iberian market, Use the wall on which it is mounted to do this., either for indoor or outdoor applications, which can even be combined with warning systems.

“Control HST not only solves the inherent reflections derived from wall mounting, but, in fact, makes the wall part of the speaker's operation - explains Rick Kamlet, senior manager commercial sound de JBL-. A single Control HST speaker can provide wall-to-wall coverage, which can reduce the number of enclosures needed to cover a space, thus reducing the total costs of the sound system”.

This acoustic enclosure is an ideal solution for stores and shopping centers, restaurants, educational facilities, leisure complexes, hotels and musical uses, which can be combined with warning systems. It is waterproof, according to IP34 standard, for outdoor use.

The system incorporates HST technology (Hemispherical Soundfield Technology) the JBL, recently developed, to provide wide coverage and eliminate primary reflection on wall, which typically causes inconsistent sound when speakers are wall mounted. This is because, when the speaker of the speaker itself is at a certain distance from the wall, Low and mid frequencies naturally tend to surround the speaker, causing reflections on the wall that mix with the original sound.

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

By using a woofer facing the wall, horizontally separated tweeters, a fitting that separates the speaker from the wall at the required distance and a housing whose shape offers adequate loading and sound dispersion, HST Control substantially reduces these inconsistencies to deliver a flatter frequency response and more balanced sound character throughout the room..

The woofer of 5 1/4″ It is made of a material called CMMD (Ceramic Metal Matrix Diaphragm), that joins an outer surface of ceramic material to an aluminum core, so Control HST has a light cone, rigid and durable offering optimal quality and detail. Besides, CMMD material offers moisture resistance.

For your part, 1 dual CMMD tweeters″ of the acoustic box have a neodymium magnet, polyurethane exterior and ferrofluid cooling to deliver high levels of output, with low distortion. Control HST is capable of handling up to 100 watts and is equipped with a locking phoenix connector (removable) of 4 pins including direct loop-through output terminals for parallel connection of another speaker.

Available in white or black (can also be painted), This speaker has a 60W transformer, with multiple positions for distributed audio systems, through high impedance lines of 70V or 100V.

With approximate measurements of 14×10 inches tall and only 7 ¼ inch deep, The JBL Control HST is supplied with a robust U-shaped fitting, weather resistant, as well as with four M6 mounting points. This speaker must be installed using this hardware in order to ensure proper spacing from the wall, as well as correct acoustic operation, and should not be mounted in corners or on vertical supports.

Fiberglass reinforced ABS housing, Painted aluminum grille and weather-resistant transducers ensure reliable operation, even under aggressive environmental conditions.
