JBL Control HST Wide-Coverage On-Wall Loudspeaker (White) JBL

The Control HST utilizes JBL’s patent-pending Hemispherical Soundfield Technology to achieve extremely wide coverage of the listening space along with eliminating the primary wall reflection that tends to cause inconsistent sound when speakers are attached to a wall. The wide hemispherical soundfield covers from wall to wall, allowing a single speaker to provide high-fidelity full-range sound to a large listening area. This can reduce the number of speakers needed for covering a space, lowering the overall cost for a sound system.

Features:

• HST Hemispherical Soundfield Technology (patent-pending)
• Provides extremely wide horizontal coverage that approaches 180°, covering a greater area with fewer speakers.
• Reduces the primary wall reflection, resulting in a flat frequency response and consistent sound character at all listening positions.
• Components: 5-1/4 CMMD woofer and two splayed ¾ fluid-cooled tweeters.
• 100 Watt power handling in direct 8ohm setting, plus built-in 60 Watt 70V/100V multi-tap transformer.
• High fidelity sound character with broad frequency response of 50 Hz – 20 kHz.
• Indoor/outdoor; black or white (-WH) color

SPLAYED TWEETERS
The dual tweeters feature aluminum diaphragms with a CMMD treat, polyurethane surround, a neodymium magnet, and fluid-cooling for high output, low distortion and humidity resistance.

WALL FACING WOOFER
The well-damped woofer incorporates a CMMD ceramic metal matrix diaphragm for a very high stiffness-to-weight ratio, high output, resistance to humidity and long-term durability.

CONTROLLED SOUND
Engineered noise cancelling allows Control HST to provide a flatter resulting frequency response along with a more consistent sound character throughout the room.

ELIMINATION OF WALL REFLECTION
The patent-pending design includes a wall-facing woofer, two horizontally splayed tweeters, a wall bracket that spaces the speaker the required distance from the wall, and a tapered cabinet that provides proper loading and dispersion of the sound. With most on-wall (surface-mount) speakers, the baffle of the speaker is some distance from the wall. It is the nature of low and low-mid frequency sound waves to wrap around the speaker, where they reflect back out from the wall, recombining with the original sound. When this occurs, some frequencies add coherently to the original sound and other frequencies cancel, causing peaks and dips in the resulting frequency response and inconsistencies from location to location within the listening space. By substantially reducing this occurrence, Control HST is able to provide a flatter resulting frequency response along with a more consistent sound character throughout the room.
