450 THX
Reference THX Home Theater Loudspeaker System
Congratulations on your purchase of the Atlantic Technology System 450 THX loudspeaker system.
With proper care, your new speaker system will provide many years of trouble-free, high quality sound
reproduction.
The System 450 THX was designed to provide accurate, uncompromised reproduction of high fidelity
music and movie soundtracks. Nothing was spared in the development of the speaker components and
cabinetry, to provide superior performance, while maintaining an elegant, compact design that is
easily integrated into the home.
What Is Home THX?
A Home THX audio system is the ultimate in sound for multi-channel home
theater systems. The system incorporates a series of patented electronic and
loudspeaker developments designed to reproduce all multi-channel sources
accurately in the home environment. The driving force behind the creation of
Home THX was the observation that, in the home environment, conventional
audio components could not accurately reproduce soundtracks as they were
originally intended. Two basic requirements were identified:
1. A need to correct the audible tonal and spatial errors caused by the reproduction of movie
soundtracks designed for playback in large theaters in the smaller environment of the home.
2. A need to more accurately reproduce the complex and competing soundfields present in multi-
channel soundtracks.
Why THX Loudspeakers?
Conventional high fidelity loudspeakers, even very expensive ones, are not ideally
suited to the demands of multi-channel soundtracks. The
Atlantic Technology System 450 THX
is ideally suited to accurately reproduce high fidelity music and multi-channel sound. Here’s why:
