Your SunÞ 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 Þ  er 
and a single long-throw driver to produce 
tight, ß 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 Þ 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 SunÞ re Subwoofer incor-
porates a driver which can move back 
and forth ap prox i mate ly Þ 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 AmpliÞ 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 Þ  er must be 
much more powerful than an or di nary 
subwoofer ampliÞ er. In fact, it has to be 
so powerful, it is almost hard to believe.
The power ampliÞ 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 ß 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 efÞ 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.
