Overview

Dual splayed tweeters for high output, low distortion, and humidity resistance, Wall facing woofer with a CMMD ceramic metal matrix diaphragm

Description

The JBL Control HST 5.25" Wide-coverage Speaker 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.

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.

Control HST is ideal for a wide variety of applications, including retail stores, restaurants, corridors, educational facilities, hospitality, music cafes, leisure venues, upscale lobbies, and other background/foreground music and paging applications. The IP-54 outdoor capability also makes it suitable for applications where an outdoor capable speaker is required.

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. 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.

The system is capable of handling 100 Watts and is equipped with a 60W 70V/100V multitap transformer. Connection is made via a 4-pinphoenix-type removable locking connector which also includes loop-thru terminals for connecting in parallel to another speaker.

A heavy-duty weather-capable zinc-rich, thick powder coated U-bracket is included. The speaker must be installed on its U-bracket for roper spacing to the wall. Do not mount the speaker directly in the corner of a room or onto a pole. It requires a wall surface in order to work properly.

Outdoor capability is enhanced by the painted aluminum grille that eliminates rusting, ABS with 10% Glass Fill cabinet, and weather-resistant drivers. The speaker is sealed-type (non-ported).
