The AC28/95 is a compact full-range loudspeaker system designed to provide maximum bandwidth and SPL in a single system package and yet be visually unobtrusive. The enclosure design allows for installation very close to walls and ceilings making it an ideal choice for under balcony, column, or wall mounting. The high frequency device is a 1" exit compression driver integrated into a newly designed 90° x 50° rotatable PT™ (Progressive Transition) waveguide providing even coverage throughout the intended listening area. The combination exhibits smooth power response resulting in extremely natural voicing. The AC28/95 utilizes dual 8" Symmetrical Field Geometry (SFG™) LF Transducers each with a copper-clad aluminum edge wound 2.5" voice coil and a copper-clad pole piece that improves performance by reducing voice coil inductance and distortion. Filtered Array Technology (FAT™) is utilized to independently control the dual woofers for magnitude and phase response resulting in smoother power response and constant coverage. To further enhance the flexibility and performance of the AC28/95, JBL engineers have designed a user selectable crossover network to ensure complete accuracy of the high-frequency coverage pattern regardless of whether the loudspeaker is being used in the vertical or in the horizontal orientation when the horn is rotated.

Applications:

The AWC62 is a compact, coaxial-driver, 2-way, highly weather-resistant full-range loudspeaker system which is ideal for speech and music-fill in a wide variety of applications, including sports facilities, racetracks, stadiums, fairgrounds, rodeos, skating rinks, themed entertainment venues, cruise ships, water parks, outdoor background music/ paging systems, swimming pools, and a wide variety of other outdoor or indoor venue types.

The AWC62 is comprised of a high-power coaxial 165 mm (6.5 in) low frequency driver and 25 mm (1 in) high frequency compression driver. The co-axial design utilizes a unique tapered pole-piece design and transitions to the cone of the low frequency driver as a large diameter pattern control horn for the high frequencies, both eliminating high-frequency beaming which is common among this category of speaker and extending pattern control to the lowest possible frequencies. The result is a coaxial speaker with wide, extremely consistent 110° coverage on a broadband basis.

Component features include a Kevlar-reinforced low frequency cone for reliability, well-damped surround for smooth frequency response, high temperature voice coil and a reduced distortion design through saturated-gap magnet geometry.

The paintable enclosure is constructed of thick, ABS plus fiberglass and is heavily braced to maximize low-frequency performance. The corrosion-resistant zinc-rich extra-thick powder coated steel grille is backed with open cell foam and high thread-count mesh, providing excellent protection in the harshest environments. The system is rated IP-56, per IEC529 when installed at minimum 5° down-tilt.

The system is equipped with a 120W 70V/100V multi-tap transformer. Connection is made via outdoor-rated terminals in a recessed terminal cup. A protective terminal compartment cover is included, along with gland nut, which forms a water-tight seal with round-jacketed cable having outside diameter between 4 mm (0.16 in) and 9 mm (0.36 in).

A heavy-duty weather-capable zinc-rich, thick powder coated U-type mounting bracket is included.

Control 312CS is an excellent addition to JBL Control 321, 322 and 328 loudspeaker systems, or any fullrange loudspeaker system that requires extended bass response.

The 322CT delivers exceptional next-generation performance in a coaxial point source design ceiling loudspeaker.
