LANSING-
LOUDSPEAKER SYSTEM
DESCRIPTION
The Altec 1230C Multi-Purpose System is a rug
gedly portable, roadworthy unit designed for
use as a stage monitor in musical sound rein
forcement applications, and as a main speaker
in P.A. reinforcement applications.
Because of its compact size, unique 8-sided con
figuration and performance features, the 1230C
solves professional-sized problems. Mounted
inside the enclosure is Altec's 12-inch 617-8A
duplex loudspeaker, well-recognized for uni
form frequency response and high efficiency,
with low and high frequency elements mounted
coaxially to produce an extremely compact yet
dynamic system. The high-frequency horn/compression driver assembly provides exceptionally
broad distribution of the high end, while the
bass driver element is known for impressively
high efficiency and durability.
The 1230C's eight sturdy, reinforced sides allow
for easy and creative positioning to optimize
sound dispersion patterns. The unit serves
ideally as a compact, on-the-road traveller, and
as a highly-efficient, reliable speaker in public
address systems.
This flexible Altec speaker system is finished in
mar-resistant textured black, with matching
black textured-knit grille and vinyl edge
protectors.
Designed for maximum strength and acoustical
properties, the enclosure is constructed of
particle board, contains acoustical damping ma
terials, and is solidly braced to complement the
theoretical design of the entire system.
