The AC28/26 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 120°x60° 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 AC28/26 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.
