ABOUT
YOUR
KLIPSCH
PURCHASE
Your
new
Klipsch
THX
Ultra2
architectural
speakers
have
been
designed
to
deliver
great
sound
while
remaining
unobtrusive
wherever
you
install
them.
The
KL
-7800-
THX
is
designed
for
Left,
Center
or
Right
channel
use
or
wherever
a
monopole
speaker
is
called
for,
such
as
surround
back
channels
in
Ultra2
configurations.
The
result
is
a
flush-mount
speaker
that
creates
a
powerful
statement
in
any
application.
The
KS-7800-THX
features
a
patent-pending
horn
array,
consisting
of
two
vertically
stacked
Tractrix®
Horn-loaded
tweet~
ers.
It
is
designed
specifically
for
surround
use
in
home
theater
applications.
The
result
is
a
flush-mount
speaker
that
creates
enveloping
ambient
sound
fields
and
localizing
specific
surround
effects
through
the
use
of
Klipsch's
proprietary
Wide
Dispersion
Surround
Technology
(WDST™).
The
careful
alignment
of
the
two
controlled-directivity
Tractrix
Horn
tweeters,
angled
opposite
one
another,
yields
an
incredibly
wide
dispersion
pattern
from
a
flush-mount
design.
