HOME THEATRE - SPEAKER SYSTEM
The SA-XR59 achieves superb reproduction by making it possible for
two amps to drive ordinary (non-biwired) speakers connected via a
single speaker cable. Conventional multi-channel amps use only one
amp per speaker in 2-channel playback, and the surround channel
amp is not used at all. But in the SA-XR59, Panasonic has applied
original technology that takes full advantage of the characteristics of
digital amps, completely synchronising the two amps in parallel so
that they can drive a single speaker using the ordinary connection
method. This capitalises on the outstanding response of the digital
amp, while the double drive power adds richness and depth. The
dual amp drive system automatically activates for 2-channel sources
and then resumes ordinary drive for multi-channel sources. There is
no need to change speaker cables to match the source.

Triple Amp with Bi-Amp/Bi-Wiring Drive
When using bi-wired
speakers with the SA-XR59,
each speaker is driven by
three amps for even higher
sound quality. This bi-amp
system drives the treble
range with a single amp and
the bass range with dual
amps, using a total of six
amps for high stereo fidelity.
Wide Frequency Range, Wide Power Bandwidth
Panasonic digital amplifiers boast a high frequency
response up to 88 kHz and a wide power bandwidth with
low distortion. And they drive the entire frequency range -
something analogue
amplifiers cannot do. The
results are amplifiers that
clearly reproduce even
high-frequency sound
components 20 kHz and
above, and unleash the
remarkable sound
potential of DVD-Audio
and other advanced
sources.
5.1ch with Dual Amp Drive (Advanced Dual Amp)
The SA-XR59 also uses its dual amp drive system to drive the
left and right front speakers in 5.1ch playback mode. This
enhances realism and ambience in movie soundtracks by
delivering high-quality sound from the left and right front
channels that play such an important role in reproducing movie
sound effects and background music.

These five-speaker units have the tweeter in the centre
and the other units arranged symmetrically around it, two
on each side. The excellent acoustic imaging provided by
this virtual coaxial configuration makes movie dialogue
extremely clear and easy to hear.

Centre Speaker
When speakers are spaced widely apart, the volume seems
to sound lower unless you're right in front of a speaker. This
is because of phase interference. To reduce this phenomenon,
we developed the new Staggered Drive System, which sets
the upper frequency range individually for the inside and
outside woofers. This reduces sound cancelling, which in
effect widens the listening area.

The use of a magnetic
fluid suppresses heat
generation in the voice
coil, eliminating any
adverse effect that heat
would have on sound
quality. This helps deliver
a sound with outstanding
linearity while also
improving durability.
2.5cm Semi-Dome
Tweeter
The speaker cabinet is
constructed of extruded
aluminum and features a
monocoque construction
for optimum rigidity. The
cabinet reduces
resonance, minimising
unwanted vibrations for
clear sound reproduction .
Resonance-Reducing
Aluminum Cabinet
A magnetic circuit with a
4-layer voice coil provides
rich bass, and an
aramid-reinforced pulp
diaphragm reproduces transparent midrange
sounds. A new woofer mounting method
reduces unwanted cabinet resonance.
8cm Slim Woofer
Super Sonic Tweeter
Thanks to a new technology, the
Super Sonic Tweeter can
reproduce high-frequency sounds
all the way up to 100 kHz – more than enough
to reproduce the breathtaking 96-kHz sounds
of 192-kHz/24-bit DVD-Audio. Because this
tweeter can reproduce even the peaks of the
high-frequency range, it replicates the
harmonics of a musical source. You get a
pure, true-to-life sound with all the nuances
and subtlety of the original.
1,428mm
If desired, you can remove
the stands and mount the
speakers on the wall. Their
slim design makes it
possible to build a sleek,
smart home cinema.
Wall-Mountable Design
The aluminum cabinet and acrylic panel combine
to form a highly attractive exterior with a polished
appearance that will complement virtually any
decor. Made of a rigid, high-quality metal, the
speaker stands provide excellent stability and
help minimise sound distortion due to vibration.
Elegant Styling and Sturdy Speaker Stands
You can adjust the height of the speakers
from 1,183mm to 1,428mm.

We gave the Aero Stream Bass-Reflex Port a smoother shape to reduce
noise from turbulent air currents when the unit is played at high
volumes. The smoother air flow helps achieve a crisp, clean bass with
minimal distortion.

A double-motion damper and a rubber edge are
used to support the diaphragm, helping produce
clear, clean bass with minimal distortion even at
high volumes. The unit is driven by a 6-layer
wound voice coil and powerful magnet which help
deliver dynamic low-frequency sounds with large amplitude.
