THX, The Standard for Theatre Sound
THX is a set of technical standards developed 15 years ago by Lucasfilm to ensure that moviegoers see and hear films as
the director intended. This comprehensive set of standards includes rigorous specifications designed to optimize
equipment,room acoustics,background noise levels,and projection and viewing angles.
The THX Sound System was developed in 1982 during the production of Return of the Jedi.Lucasfilm’s technical experts
began to consolidate existing performance standards into a new system which included theatre acoustics as well
as sound
reproduction equipment.THX (named after Lucas’ first feature film, THX 1138) is a sound system designed specifically
to reproduce film sound exactly as it was recorded by the filmmaker.
The system was created to complement advances made by Dolby Laboratories in encoding and decoding sounds in the
sound track. The THX Sound System concentrates on the playback chain from the decoder through amplification,
speakers and theatre acoustics.
A certified THX theatre carries several important advantages for the moviegoer.The audience enjoys a more naturally
balanced sound that uniformly reaches every seat in the auditorium, improved dialog intelligibility and decreased bass
distortion.Better stereo localization makes the sound appear to travel across the screen with action.The result is the
reproduction of the same clear,dynamic sound originally created by the filmmaker.
In 1985, Lucasfilm’s THX Division began researching the reproduction of movie soundtracks in the home. Testing
revealed a startling difference in sound quality and character between home theatres and THX theatres.Home THX was
created to solve this problem.
Circuitry was designed to accurately translate the sound from movie environment into the home,correcting the tonal
and spatial errors that occurred. Then refinements in designs were researched: most hi-fi equipment was designed to
reproduce only two channels of sound in home,not the four, five or more channels present in a movie soundtrack.
THX certified speakers are designed to provide accurate reproduction of the soundtrack in the home environment.
Sonance Cinema™LCR front channel speakers provide improved dialogue intelligibility as well as imaging. A system of
THX ULTRA certified components assures you of the ultimate home theatrical experience.
INTRODUCTION
Congratulations on your choice of the Sonance Cinema™Two Subwoofer System. Sonance Cinema
systems let you hear movies the way the directors intended them to be heard on the big screen. Your
system will allow you to enjoy vastly improved dialogue intelligibility, superior on-screen sound
localization, enveloping surround sound and incredibly wide frequency response and dynamic range.
The décor friendly, sonically superior Sonance Cinema Systems meet the highest standard for accurate
reproduction of cinema soundtracks and are compatible with all Dolby Digital sound tracks.
This state of the art sound system literally disappears in your room.Each speaker protrudes just threequarters of an inch from the wall … even the subwoofers!
Cinema Two LCR (left, center,right) speakers are THX® ULTRA certified and employ no compromise
audiophile grade crossovers,resulting in a virtually seamless transition between drivers for a smooth
and accurate sound stage. Open, detailed, and transparent, with a natural tonal balance and precise
stereo imaging, the main speaker arrays of the Cinema Two can fill a room with sound without the
usual speaker box clutter.
The three-driver array (two midranges flanking the tweeter) achieves consistent fidelity with a narrow
vertical dispersion pattern to minimize the influence of room acoustics. Cinema Two LCRs feature the
exclusive Cinema Acoustic Alignment Device (CAAD),a tilting/rotating midrange/tweeter plate which
allows the speakers to achieve maximum sonic performance in a variety of installations.An eight-inch
woofer completes the speaker system.
Cinema Two LCR and SUR speakers fit in standard 2"x 4" frame walls. Cinema Two LCR speakers are
also magnetically shielded to eliminate interference with TVs,clocks, or other electrical devices.
Cinema Two SUR speakers are THX® ULTRA certified and feature dual tweeter/midrange arrays and
eight-inch woofers. These surrounds are configurable in either bipolar or dipolar mode to achieve the
desired performance.Bipolar configuration is optimal for reproduction of the diffuse ambient content
of soundtracks. The dipolar setting, in some instances,provides greater localization of sound effects.
Changing configuration is easily achieved by simply changing one connector. Like the LCRs, the
surrounds fit into standard 2"x 4" stud walls.
Cinema Two SUB subwoofers provide powerful bass to complete a truly visceral movie experience.
These in-wall sub systems are capable of shaking the foundation of the most massive fortress of
solitude,without being seen.
The Cinema Two SUB includes four ten-inch aluminum drivers and a Sonamp Cinema 2120 amplifier
with a built-in crossover, phase adjustments. and mode switches. Integral to the Cinema Two System
are the specially designed back boxes which assure outstanding performance.

IMPORTANT SAFETY INSTRUCTIONS
When using your Cinema speakers, basic safety precautions should
always be followed to reduce the risk of fire, electric shock, and
injury to persons, including the following:
1. Read and understand all instructions.
2. Retain the safety and operating instructions for future reference.
3. Follow all warnings and instructions in this manual and marked
on the product.
4. Any service or repair required must be performed by qualified,
factory authorized personnel.
5. Do not use this product in a high humidity environment or near
water, for example a wet basement, wet bar, or swimming pool.
6. Never touch the drivers or push objects of any kind into this
product through the grilles.
7. Always provide adequate ventilation for the Sonamp 2120.
Allow a minimum of one inch above and three inches behind the
amplifier. Do not block cooling vents on the amplifier case.
8. The amplifier should be situated away from heat sources such
as heat registers, radiators, stoves, or other appliances that
produce heat.
9. The amplifier should only be connected to a power supply of
the type marked on the back panel. The power supply cord
should be routed to avoid damage from contact with sharp
objects or being stepped on.
10. Unplug the amplifier during thunderstorms or when the
system will be unused for extended periods.
11. Exercise care to avoid spilling liquids on or in the amplifier
or speakers.
12. Do not place the amplifier on an unstable table, stand, or cart.
Improper placement of the amplifier may cause it to fall on
an adult or child, causing serious injury and damage to
the amplifier.
