DESCRIPTION
m
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. |
