ASB6128V is a high power subwoofer
system comprised of two 460 mm
(18 in) NDD Neodymium Differential
Drive low frequency drivers in
“V”-loaded configuration. The compact
cabinet provides a common height with
some of the AE Series full-range loudspeaker models, for easy arrayability of
multiple cabinets with the subwoofer in
the center. The “V”-loaded baffle provides additional sensitivity in the deepbass region as well as tighter clustering
of drivers for better mutual coupling in
arrays. A deep cabinet design allows
sufficient internal volume for extended
low frequency bandwidth with minimum frontal profile. The rectangular
cabinet is fitted with M10 threaded suspension points. Pre-engineered array
bracketry is available.
ASB6128V is part of JBL’s AE
Application Engineered Series, a
versatile family of loudspeakers for a
wide variety of applications.
