The AM7212/00 is a high power, lightweight, 2-way, full-range loudspeaker system comprised of the JBL Differential Drive dual voice coil and dual magnetic gap 2262H 300mm (12 in) low-frequency driver and 2432H high-frequency 38 mm (1.5 in) exit, 75€mm (3 in) voice-coil compression driver. The large format Progressive Transition waveguide provides excellent 100° x 100° 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 offaxis response enhances arrayability.

The enclosure is constructed of multi-ply 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 AM7212/00 is part of JBL’s AE€Series, a versatile family of loudspeakers intended for a wide variety of applications.
