DESCRIPTION
The permanent installation of compact, "packaged"
loudspeakers in architectural spaces has grown increas­
ingly popular in recent years. Sound system designers
sparked this popularity through their increased creation of
high output, concert quality loudspeaker systems. These
systems provide a level of quality desired by the perform­
ing arts and touring sound industries. The introduction of
trapezoidal enclosures enable sound system designers to
locate more loudspeakers in a smaller physical space,
thereby increasing output and creating an effective "point
source" cluster.
While most of these systems reproduce amplified
music with the intensity and wide bandwidth suitable for
concert quality reproduction, they typically lack the direc­
tivity to provide highly intelligible, natural sounding speech
with adequate gain-before-feedback. This compromise is
completely unacceptable in a performing arts center or
house of worship.
The Altec Lansing DTS645-8AF loudspeaker was
created to provide high output levels for full-range music
reproduction while offering a very directive output for
highly intelligible speech in even the most reverberant ar­
chitectural spaces. Altec Lansing's engineers have created
a new Duplex® coaxial loudspeaker which physically aligns
the high and low frequency drivers creating a true point
source device. This concept is the driving force behind the
DTS-series of arrayable loudspeaker devices.
Complementing the DTS645-8AF's powerful
performance is a trapezoidal cabinet which allows for
flexible arraying. The integral L-track flying hardware
facilitates quick, easy, and repeatable installations.
