What’s THX?
THX is a series of demanding performance standards and specific tech-
nologies developed by Lucasfilm Ltd. (of Star Wars fame). Equipment that
meets the rigorous THX standards will deliver performance in your home
that matches as closely as possible what the director/artist/engineer heard
and saw during the final mixing of the source material. Please note that
THX is not a separate surround sound decoding format. THX-certified
equipment enhances every viewing and listening experience, regardless of
the surround format used.
THX Select standards are based upon a room size of 2000 cubic feet (L x W
x H). This does not mean these components must be used in a rooms this
size. The room sizes simply provide a frame of reference, as they indicate
that these systems must deliver a minimum level of performance in this
specified room size. Your System 4200e is THX Select certified. For more
information, visit the THX website at www.thx.com.
Individual Component Descriptions
Model 4200e LR Front Channel Speakers
The Model 4200e LR Front Channel Speakers (Figure 1) are high-perfor-
mance 2-way systems intended for use with a quality subwoofer, such as the
Atlantic Technology Model 642e SB box-type subwoofer. Each speaker con
-
tains two GLH (Graphite Loaded Homopolymer) 5 ¼” (135mm) woofers
and an advanced 1” (25mm) ferrofluid-cooled, damped silk dome tweeter
with a powerful neodymium magnet structure. The drivers are configured
in a D’Appolito array (midrange-tweeter-midrange alignment) This verti
-
cal arrangement of drivers provides wide left to right coverage of sound
while limiting the floor and ceiling reflections that color the sound. These
components are mounted in an acoustically inert internally braced MDF
enclosure. The LR speakers are magnetically shielded so they may be placed
close to a TV set without concern.
Acoustic Controls
System 4200e LR speakers include unique acoustic controls to help maxi-
mize their performance in your room. These controls are explained in
greater detail on page 8.
Model 4200e C Center Channel Speaker
For accurate reproduction of a multi-channel soundtrack, the three front-
channel speakers must have the same sonic signature. Therefore, the 4200e
C Center Channel speaker contains the same driver complement as the
respective matching LR speakers (see Figure 2). They are both designed
for use with a dedicated subwoofer and include the same unique acoustic
controls mentioned on page 8. The 4200e C is designed to be placed hori
-
zontally. They are also magnetically shielded and can be placed directly
adjacent to your TV set with no adverse effects on the television’s picture.
The 4200e C can be tilted on its dedicated base to provide optimum sonic
coverage of the listening area.
