The AC15 is an ultra-compact fullrange 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 AC15 utilizes a
5.25" Symmetrical Field Geometry
(SFG™) LF Transducer with a copperclad aluminum edge wound 1.5" voice
coil and a copper-capped pole piece
that improves performance by reducing
voice coil inductance and distortion.
The rugged multi-ply 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
The rugged plywood enclosure
features JBL’s textured DuraFlex™
finish and is equipped with a heavy
duty powder coated steel, foam-backed
grille.
