Introduction
The NuForce 53-BT is an active loudspeaker featuring high-fidelity (apt-X and
AAC)
8/uetooth
wire-
less connectivity. It's designed
to
fit
your
modern lifestyle and decor while also delivering a level
of
audiophile-quality
that
many dedicated enthusiasts have longed for-wirelessly.
8/uetooth (BT)-enabled devices are
now
commonplace,
but
most have always had one weakness -
mediocre sound quality. While many
BT
speakers
work
well for basic applications, they really aren't
able
to
deliverhigh quality
sound-at
least
not
by
NuForce standards.That's becausethey
emp
l
oy
the
old and
inferior
"SBC"
codec
.l
ncontrast.
the
NuForce
S3
-
BT
is based on the latest"apt-X" codec, which
was developed
to
enable
the
kind
of
crystalline sound
that
NuForce customers have come
to
expect.
Regardless
of
how
the signal
is
delivered
to
it, every speaker
is
still a speaker
at
its core, so sound
quality always dependends on the fundamental principles
of
speaker design, including
the
materials
used.
We
kept this in mind when designing the
S3-BT,
which we
built
upon a platform
of
advanced
design and superior components. The woofer is constructed using a proprietary "anti-resonance"
cone technique and powerful magnet assembly, while the
tweeter
is a custom soft-dome design
known among audiophiles
for
offering the lowest distortion and smoothest natural response.
In its "standard mode," out-of-the-box
form
, the
S3-BT
with
apt-X codec offers exceptional
8/uetooth
performance.
Even
so,
for
those hardcoreaudiophiles
who
demand the highestlevel
of
wireless fidel-
ity, we've made the
S3-BT
upgradeable by including an additional set
of
analog inputs in the design.
This allows
the
user
to
bypass the standard 8/uetooth connection in favor
of
using NuForce's
own
Air
DAC
wireless system,
or
even a wired connection.
The advantage
to
using the NuForce Air
DAC
is
that
it
was designed
to
achieve a level
of
true
16-bit
performance
that
simply isn't possible
with
the
8/uetooth
standard.
As
good
as
8/uetooth w
it
h apt-X
is,the
S3-BT
mated
with
the
NuForce Air
DAC
sounds even better.
Whetheryou choose
to
use the
S3-BT's
"standard mode"8/uetooth wireless,
or
upgradeits sound
with
the Air
DAC
system,
the
S3-BT
offers a much needed, audiophile-grade alternative
to
mediocre wire-
less sound. Don't settle
for
less than
the
best any longer: get
the
clarity, detail and power all NuForce
products are known for, with the NuForce
S3-BT.
