Sunfire HRS-SAT4 User Manual page 4

Overview
The HRS-SAT4 and HRS-SAT4C are
high performance loudspeakers, specifi-
cally designed to provide high output and
high performance for your home theater.
Years of research and decades of ex-
perience have gone into these amazing
loudspeakers.
Sunfire created the category of small-
box, high-power subwoofers more than
a decade ago with the original True
Subwoofer. This design relies on high-
pressure, "High Back-emf" technology
that provides very high bass output from
a very small box. When migrating this
subwoofer technology to the midrange
and high frequencies on these HRS loud-
speakers, you get the same advantages:
high output, small size, high efficiency,
and years of trouble-free operation.
Woofers
The "Trifilar" voice coil (actually 3
dual voice coils wound in parallel) has
a much higher output than conventional
multi-layer voice coil designs, and is
also significantly lighter. This, combined
with the lightweight and incredibly-strong
Kevlar cone, means that the driver
®
responds very quickly. As a result, drum
kicks, and other percussive effects will
sound tighter and more lifelike. Having a
lightweight woofer means that it has im-
proved top-end response. This makes for
smoother integration with the tweeter in
the critical upper midrange, lower treble
range – where much of the vocal informa-
tion lives. As a result, vocals and dialog
sound very natural – not muffled or tinny.
The woofer's 1" excursion is up to four
times that of conventional woofers, and
provides the highest power handling in
its class.
The cast aluminum basket offers more
rigidity than the typical stamped variety.
When driven at high volume, they will not
flex, and the result is tight bass at high
volume, with very low distortion.

Tweeter
The tweeter used in both the center
and surround loudspeakers represents
a unique approach to tweeter design
that results in unrivaled performance. It
shares design elements with tweeters
found in very expensive European loud-
speakers, and has a frequency response
that is flat to above 20 kHz for crystal-
clear detail from any source.
The 1" ring radiating silk dome offers
instantaneous response and wide disper-
sion. The tweeter's vented back chamber
contributes to high power handling,
improves frequency response with lower
distortion, and provides superior transi-
tion from high frequencies to the critical
midrange.
Cabinet and baffle
The woofer(s) and tweeter are mounted
to a cast aluminum front baffle that is
clamped to the cabinet from the rear,
forming a fully-sealed enclosure. This
clamping design produces a stiff cabinet
that is very resistant to vibration, result-
ing in tight bass response, high fidelity
reproduction, and high output for music
and movies.
Nine layers of paint and clear coats
provide an elegant finish with protection
and scratch resistance, and matches the
finish of the HRS subwoofers.
Optional satellite stand
Specially designed for the
HRS-SAT4, these optional
stands follow the cabinet
shape, and produce an inte-
grated, one-piece look. The
stand has an attractive high-
gloss lacquered base and
painted aluminum column.
Speaker wires are hidden
inside the column, for a
sleek finished product.
