Overview
The HRS-SAT4BIP surround loud-
speakers are specifically designed to pro-
vide high output and high performance
for your home theater. Years of research
and decades of experience 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 woofer of
these HRS surround loudspeakers, 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 tweeters used in the surround
loudspeakers represent a unique ap-
proach to tweeter design that results in
unrivaled performance. It shares design
elements with tweeters found in very
expensive European loudspeakers, with
a frequency response that is flat to above
0 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 and tweeters 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 scratch-resistant finish
that matches the HRS subwoofers and
loudspeakers.
