The AC25 is an ultra-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" dome tweeter integrated
into a newly designed 90° x 90°
waveguide providing even coverage
throughout the intended usage area.
The combination exhibits smooth
power response resulting in extremely
natural voicing. The AC25 utilizes dual
5.25" Symmetrical Field Geometry
(SFG™) LF Transducers each with a
copper-clad aluminum edge wound
1.5" voice coil and a copper-capped
pole piece that improves performance
by reducing voice coil inductance and
distortion. In addition 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.
The rugged multiply hardwood
enclosure is designed to work in the
vertical plane as well as in the
horizontal plane. Mounting points are
provided for an optional U-bracket and
for an OmniMount®type bracket.
The rugged plywood enclosure
features JBL’s textured DuraFlex™
finish and is equipped with a heavy
duty powder coated steel, foam-backed
grille.
