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.

The 515-G Series loudspeakers incorporate
Altec's 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, yields a speaker capable
of very high sound pressure levels and good reliability.
The hom-loaded design of the 515-G Series ensures
that the 515-8GHP performs optimally in all
vented horn enclosures.

* AES power rating (measured Power = E^/R, using Pink Noise with a crest factor of 6 dB and a band-limit of 60 to 600 Hz).

** Low frequency limit is the 3 dB down point using the particular cabinet and the Thiele/Small parameters of the loudspeaker.
*** Measured in the free-fieid at 4.0 feet (1.2 m) on axis with one watt (Power = E^/R) of pink noise band-limited from 100 to 1000 Hz.
