418-8H
The ALTEC 418-8H Musical Instrument Loudspeaker is a rugged, 15” loudspeaker designed
for use in musical entertainment systems of moderate size and coverage area where true
high-fidelity reproduction must be combined with high power output.
The
418-8H
has
a
heavy
permanent
magnet,
a
structurally
reinforced
die-cast
aluminum
frame, a 3"-diameter edge-wound voice coil of copper ribbon and a cone suspension having
exceptional compliance. It is sealed against dust and dirt.
The smooth response and excellent linearity of the 418-8H loudspeaker is achieved by strict
adherence
to
precision
design
and
manufacturing
tolerances.
The
axial
retention
of
the
voice
coil
in
a
magnetic
field,
uniform
over
the
full
excursion,
ensures
clarity
of
music
reproduction at high power levels. The low cone resonance, when the speaker is mounted
in
a
suitable
enclosure,
virtually
eliminates
all
'doubling'
or
self-generation
of
unwanted
harmonic components.
The 418-8H has a continuous power rating of 150 watts and a frequency response from 45
to
8000
Hz.
Its
design
provides
high
efficiency,
high
linearity,
low
distortion,
wide
range
and optimum cone resonance.
