The AM5215/26 is a medium power, lightweight, 2-way, full-range loudspeaker system comprised of the JBL Differential Drive dual voice coil and dual magnetic gap 265H-1 380 mm (15 in) low frequency driver and 2408H-1 high-frequency 38 mm (1.5 in) exit, 38 mm (1.5 in) voice-coil compression driver. The large format Progressive Transition waveguide provides excellent 120degrees x 60degrees coverage. The waveguide is rotatable so the loudspeaker system can be used in either the vertical or horizontal orientation. High-slope passive networks minimize band overlap. Well-controlled off-axis response enhances array ability. The enclosure is constructed of multiply birch coated in JBL's rugged DuraFlex finish and is heavily braced to maximize low-frequency performance. The trapezoid enclosure is fitted with fifteen M10 threaded attachment points and utilizes a 14-gauge steel grille internally lined with acoustically transparent foam to provide additional driver protection and give a very professional appearance. The AM5215/26 is part of JBL's AE Series, a versatile family of loudspeakers intended for a wide variety of applications.
