The PZ700A and LXD700A series feature SRS TruSurround
XT, a sound-enhancing system that expands the acoustic
field, making it possible for these two speaker systems to
produce a virtual 5.1-channel surround effect that wraps
the listener in a pure, clear sound. Developed by SRS
Labs, Inc., SRS TruSurroundXT is a 3D sound reproduction
technology that's based on the Head-Related Transfer
Function - part of a theory that concerns the relationship
between frequency change and the human ears' ability to
determine the direction of a sound. This technology solves
the problem of narrow "sweet spots", a shortcoming of
ordinary stereo reproduction systems. Used in the PZ700A
and LXD700A Series, it helps provide expansive surround
sounds across a wide listening range.

A Pure, Clear Sound That Seems to Come Right From The
Screen
The new speaker units we
developed for this system offer
outstanding clarity, rich bass,
and superior sound localisation
in the medium frequency range.
We also developed speaker
diaphragms made of eco-friendly bamboo fibres, achieving both
a crisp, transparent treble sound and excellent environmental
performance. A unique, improved passive radiator in the woofer
also helps produce a clear, robust bass sound.
The new Advanced Ultra-Slim Speaker Unit
reproduces sounds all the way down to 350Hz -
the kind of deep sound, such as a male baritone
voice, that was handled by the woofer in
conventional systems. Even with its narrow
aperture, the new speaker unit has superb
directional characteristics, so everyone in the
room enjoys outstanding sound quality.
ADVANCED ULTRA-SLIM
SPEAKER UNIT
The woofers use an enhanced passive radiator
system to deliver an incredibly deep, clear
sound. Using asymmetrical, contoured edges to
prevent the harmonic distortion that can occur
with conventional passive radiator systems,
this enhanced system delivers a clearer sound
than bass reflex systems of the same size.
