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.
