Your Sunfi re True Subwoofer EQ Soli-
tiare is designed to give you the best pos-
sible low-fre quen cy sound quality for your
Home Theater ex pe ri ence. It in cor po rates
a tre men dous ly powerful built-in am pli fi er
and a single long-throw driver to produce
tight, fl oor-rumbling, denture-rattling bass
that you can feel as well as hear.
The subwoofer is available in two ver-
sions, and this manual covers both:
Solitaire 12 is a 13 inch cube, with an
output greater than 113 dB peak
SPL, 16 Hz to 100 Hz.
Solitaire 10 is an 11 inch cube, with an
output greater than 107 dB peak
SPL, 18 Hz to 100 Hz.
The subwoofer has an automatic
equalization system which will tailor the
subwoofer output to compensate for
any room effects. It also has a manual
equalization mode. An Equalizer Authority
control allows you to adjust the amount
of automatic equalization, and overide it
if required.
The subwoofer has an adjustable high
cut fi lter and a choice of speaker-level
or line-level inputs for easy in cor po ra tion
into existing systems, or as part of a
subwoofer/satellite speaker com bi na tion.
Controls for adjusting the volume,
crossover frequency and phase, allow
the subwoofer to be perfectly matched
to any listening environment and audio
components.
The Driver
To have lots of bass requires moving
lots of air. Your Sunfi re Subwoofer incor-
porates a driver which can move back
and forth ap prox i mate ly fi ve times more
than a normal sub woof er. This gives it a
lot of air moving capacity which allows for
majestic bass per for mance.
The Amplifi er
The large movement range of the
driver creates greater air pressure inside
the box than a con ven tion al subwoofer.
There fore, the drive am pli fi er must be
much more powerful than an or di nary
subwoofer amplifi er. In fact, it has to be
so powerful, it is almost hard to believe.
The power amplifi er within the Solitaire
12 Subwoofer is capable of de liv er ing
over 1,500 watts into a 3.3 ohm resistor
(the driver voice coil re sis tance). The
Solitaire 10 is capable of delivering 1,250
watts. When the same full output is ap-
plied to the driver, however, the enor-
mous back-elec tro mo tive force gen er at ed
as a con se quence of its large motion and
giant magnet, causes the current fl ow to
be much less than if it were a 3.3 ohm
resistor. It is this singular property of the
driver that allows the subwoofer to be ap-
prox i mate ly ten times more effi cient than
a subwoofer this size would nor mal ly be.
A compressor circuit kicks in au to mat i-
cal ly if the input signal level reaches a
level that would overload the driver. This
maintains a ceiling on the output without
clip ping. If the input signal is driven even
further, a ‘soft clipping’ circuit is enabled.
This allows the subwoofer to put more
sound into the room to satiate the power
hungry user, but without distortion or
damage to the subwoofer. Thus, for ex-
plosive scenes in movies, this pro duc es
extremely high sound pressure levels
(SPL) in your room without the drivers
banging against the mechanical stops.
