DESCRIPTION
The ALTEC 601-8D Duplex Loudspeaker System
is a two-way loudspeaker with high- and low-
frequency speakers coaxially mounted in a
single frame. The dual magnet structures allow
each speaker to be magnetically, electrically
and mechanically independent. Coaxial driver
arrangement also provides the effect of an inte­
grated source of full-range sound. All frequen­
cies are propagated through a common
'window' to ensure good stereo imagery when
multiple 601-8D's are used.
The high-frequency section has a voice coil of
edge-wound aluminum ribbon attached to an
aluminum diaphragm and loaded with a sturdy
exponentially expanded multicellular horn. The
low-frequency cone is driven by a voice coil of
edge-wound aluminum ribbon, and is sup­
ported by a high-compliance cloth surround.
The 601-8D is a fine loudspeaker for general-
purpose sound reproduction applications. It is
designed to operate in enclosures as small as
2.5 cubic feet, and its relatively small physical
size permits excellent wide-range performance
in environments which would otherwise utilize
lower quality, single-driver speakers.
