JBL - Constant Beamwidth Technology™ Two-Way Line Array Column Speaker, Wall Mount-Each - White

The CBT 70J-1, with Constant Beamwidth Technology™, represents a breakthrough in pattern control consistency, utilizing complex analog delay beam-forming and amplitude tapering to accomplish superior, consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of straight form-factor column speakers. The CBT 70J-1 combines Constant Beamwidth Technology with a physical J-shaped curving, resulting in a very well controlled progressive line array with asymmetrical vertical coverage. The asymmetrical coverage produces a higher concentration of sound with a tighter pattern from the upper half of the array and a lower concentration of sound with a broader vertical pattern from the lower half of the array.

Adjustable Coverage to Fit the Application

The innovative coverage adjustability allows switching between broad and narrow vertical coverage settings to allow matching the coverage and throw requirements of the application. Coverage can be easily switched in-venue with the speaker already installed. This innovation allows a single loudspeaker model to excel in an extremely wide variety of project types.

User Variable Voicing

The voicing can be set to match the application through a Music/Speech switch. The Music setting provides flat frequency response, while the Speech setting produces a mid-range presence boost to provide clear, intelligible speech even at the longest throw distances, along with increased midrange sensitivity for higher midrange maximum output capability

Low Frequency Drivers

The low frequency drivers are lightweight dual magnet neodymium motors with 38 mm (1.5 in) diameter voice coils. The dual magnet system provides maximum flux in a compact package. The magnet structure is magnetically shielded and the pole tips are magnetically saturated for lower flux modulation and minimum distortion. The 16 mm (0.63 in) long coil provides high linear drive and high power handling in a compact driver.

High Frequency Drivers

The high frequency driver features a dual magnet neodymium structure for maximum sensitivity. The tweeter is encased for weather resistance. The drivers are magnetically shielded to allow close placement CRT monitors.

SonicGuard

Dynamic SonicGuard™ protection on the high frequency section minimizes distortion at high drive levels by limiting driver excursion dynamically. This maximizes music clarity and speech intelligibility at high drive levels while protecting the drivers from damage due to occasional overpowering.

Bracketry

A swivel (pan) / tilt wall-mount bracket is included, plus ten M6 inserts on the back panel fit the spacing of common third-party mounting brackets, or can be utilized to suspend the speaker using forged shoulder steel eyebolts or swivel mounting rings, providing installation versatility.

Weather Resistant with optional panel cover

CBT 70J-1 can be installed either indoors or outdoors. IP-55 rated, per IEC529, when installed with optional MTC-PC2 panel cover. UV, moisture and 200-hr ASTM G85 acid-air/salt-spray resistant. The drivers are weather-treated, the fiberglass reinforced ABS cabinet is excellent for outdoor applications, external screws are stainless steel and the painted aluminum grille resists rusting in the harshest conditions.

Mounting Bracket

Included swivel (pan)/tilt wall bracket provides continuously variable +/-80 degree left-right swivel aiming
