DESCRIPTION
The Altec Lansing 515-G Series loudspeakers
are designed for unsurpassed performance when
used in low frequency horn and vented horn en-
closures. They are the highest performance low
frequency drivers that Altec produces. When the
ultimate in sound quality, efficiency, and response is
needed, the 515-G Series is the answer.
In-depth research into the properties of low
frequency horns and vented horns has produced
three drivers which are optimum for horn applications.
When coupled with an appropriate horn, the
515-G Series loudspeakers provide the best possible
combination of wide response, high efficiency, low
distortion, and directivity control. В
The 515-G Series loudspeakers incorporate
Altecs largest magnet structure, an edgewound
aluminium flatwire voice coil, a light cone assembly,
and a-low distortion cloth suspension.
The 515-8G and 515-16G carry on the
Altec Lansing 515 tradition. The 515-8G provides
extended bass response and extremely high lin-
earity for optimum performance in vented horn
enclosures. The 515-16G is intended for applica-
tions similar to those for the 515-8G, but where
16 ohm impedance and increased sensitivity is
needed, as in dual loudspeaker enclosures such as
the Altec 210/211 and 817A vented horns.
Both loudspeakers are constructed of materials simi-
lar to 515's of earlier years to produce the sound
made popular in theater and studio applications.
The 515-8GHP is the most efficient loud-
speaker Altec has ever produced. This, coupled
with high power handling, vields a speaker capable
of very high sound pressure levels and good reliability.
The horn-loaded design of the 515-G Series ensures
that the 515-8GHP performs optimally in all
vented horn enclosures.
