System 350 THX

High Performance Home Theater
Loudspeaker System

Congratulations on choosing Atlantic Technology Home Theater Components. The
System 350 THX is engineered to bring you as close as possible to the acoustic
environment of the finest THX theaters. When properly set up and balanced, the
Atlantic Technology THX speaker system, coupled with THX ancillary components,
allows you to fully experience movies at home the way filmmakers intended.

Conventional high fidelity loudspeaker systems, even very expensive ones, are not
ideally suited to the demands of multichannel movie soundtracks. In order for the
speakers to accurately reproduce what the film director created on the dubbing stage,

they must meet specific design parameters developed by
the motion picture industry. To achieve this, George
Lucas and Lucasfilm originated and perfected Home
THX, a strict set of standards and guidelines for home
theaters, so that they may emulate the original dubbing
stage. When properly followed, these guidelines address
and correct the problems of overly bright or harsh

soundtracks, unintelligible dialog, and poor localization of sounds. With Atlantic
Technology’s System 350 High Performance THX Home Theater Loudspeakers you will
experience all the impact, full frequency response, and enveloping soundfield of your
favorite films for the first time.

The 

Model 351 LR Front Channel Speakers

 incorporate two 5-3/4" polypropylene

woofers in a D’Appolito configuration with two 3" midrange drivers and a 1" ferrofluid-
cooled fabric dome neodymium tweeter in a separate sub-enclosure. The crossover is a
premium fourth-order design with a conjugate network. Gold 5-way binding posts are
provided to ensure easy connection with a wide variety of speaker cables. The tall,
narrow dimensions of the cabinet, together with the driver configuration, optimizes
horizontal dispersion and vertical directivity so important to the proper reproduction
of the soundstage.

The 

Model 353 C Center Channel Speaker

 features the same driver complement,

crossover, and cabinet volume as the 351 LR making left to center to right pans virtually
seamless. The horizontal dispersion and vertical directivity characteristics of the speaker
are maintained by using a D’Appolito configuration of two 3" midranges and 1" tweeter
identical to the 351 LR. A tiltable base was developed to provide a variety of placement
options either above or below the picture source without compromising performance.
