INTRODUCTION
Congratulations on choosing The Sub by Sonance
®
, the
third- generation, freestanding subwoofer from the leader in
architectural audio products. All Sonance speakers deliver
outstanding fidelity and imaging for all audio source material -
they let you hear movies the way the directors intended them to
be heard on the big screen. In addition, THX certified
subwoofers provide the highest level of bass performance when
playing any music source. The extended low frequency
response of The Sub completes any premium sound system.
By relieving the main amplifier and speakers of the need to
reproduce low frequencies, there will be an instant improvement
in their performance as well. The result will be dramatically
enhanced frequency response and dynamic range from your
sound system. Compact and sonically superior, The Sub by
Sonance meets the highest standard for accurate reproduction of
cinema soundtracks and is compatible with all Dolby Digital®,
THX® , and Dolby Pro-Logic ® systems.
The Sub is uniquely designed for maximum placement
flexibility and can be positioned wherever optimum sound or
décor considerations dictate, even inside a cabinet (with open
front). All controls are located on the front, as are the four
tuned ports with flared openings. No down- or rear-firing
driver limits your placement options. Electromagnetic shield-
ing prevents interference with video reproduction.
The Sub provides the powerful bass essential to complete a
truly visceral movie experience. Employed singly or in pairs,
these sub systems are capable of shaking the foundation of the
most massive fortress of solitude.
The Sub’s 12" driver features a high-density cone with
rubber surround, rigid steel frame, long-excursion 3" diameter
voice coil, and massive 60-oz magnet. The 60-lb. cabinet is
free of degrading resonances thanks to its cross-braced
construction of 3/4" and 1-1/2" (MDF) medium-density
fiberboard and isolation of the amplifier in an integrated back
box. Its high-efficiency 150-watt (RMS) amplifier attains
undistorted output levels exceeding 105 db.
The Sub contains both an active crossover with a fixed 12 dB
per octave slope at 250 Hz for THX® processors and a variable
12 dB per octave 45-150Hz crossover for user preference. Both
provide a clean transition between The Sub and the main
speakers. The Sub can be easily integrated with anything from
full-range speakers to miniature satellites thanks to phase
inversion and crossover bypass switches, wide-range crossover
frequency (45-250 Hz) and level controls, as well as line level
and speaker level inputs and outputs.

THX Select®, A New Reference Standard for Smaller Rooms
THX Select brings the clear advantage of THX performance to a new
class of home theatre components, those designed for use in typical
living room/family room environments. Like the original Home THX
Program (now distinguished as THX Ultra), THX Select establishes
specific performance criteria for creating the ultimate cinema experience
in a home setting. However, where the original Home THX specifications
must take into account viewing spaces of 3000 cu. ft. or more, THX
Select criteria are specifically calibrated to define reference level
performance in room volumes of about 2000 cu. ft. Compared to most
other components in the same price range, THX Select components not
only offer exclusive features (like THX Mode processing), but also
provide higher levels of overall audio performance. Though THX Select
loudspeakers are available in a variety of sizes and designs, all have
been painstakingly tested and evaluated by THX engineers to certify
that each will meet stringent performance standards when used in a
typical living room setting. Whether you listen to movie soundtracks
or new 5.1 channel surround music recordings, THX Select gives
you full confidence that each certified component will perform
as “the best in its class.”
• THX Select front speakers (Left, Center and Right) have a virtually
identical sonic signature. This ensures precise positioning of sonic
images and consistent panning dynamics. Also, horizontal dispersion
is wide and even to cover all listening positions with consistent,
full sound.
• THX Select loudspeakers exhibit a simplified and refined directivity
pattern, one ideally suited to smaller room volumes and shortened dis-
tances between listeners.
• THX Select surround loudspeakers employ a variety of designs,
including dipole, bipole or monopole, to allow compact cabinets and
placement flexibility.All designs maintain flat power response at the
listening position while exhibiting ideal tonal balance and listening clarity.
• THX Select loudspeaker systems produce dynamic peak levels of
105db in a 2000 cu. ft. room. This standard allows for accurate
reproduction of transient peaks in digital soundtracks.
