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 indi- cate that these systems must deliver a minimum level of performance in this specified room size.Your System 4400 is THX Select certified.For more information, visit the THX website at www.thx.com.

Model 4400 LR Front Channel Speakers

The Model 4400 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 4400 LR speakers include unique acoustic controls to help maximize their performance in your room. These controls are explained in greater detail on page 8.

Model 4400 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 4400 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 4400 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 4400 C can be tilted on its dedicated base to provide optimum sonic coverage of the listening area.
