3. The Home THX Audio Speaker System

Your choice of an M&K Home THX Audio speaker system assures you of achieving the state
of the art in home theatre music and video reproduction. The precise and exacting standards
developed by Lucasfilm's Home THX division assure that you will hear every element of film
sound — from the softest brush of an object against an actor's clothing to the awesome impact
of effects such as an exploding planet — with the same sonic quality heard by the film's director
and sound designer as they created the final mix of sound on the studio's dubbing stage.

To do this in a home environment requires different equipment and standards than are found
in a THX motion picture theatre. The standards developed for Home THX Audio are critically
important to achieving the following performance attributes:

- wide frequency range, extending to the limits of audibility

- smooth, naturally balanced overall sound

- excellent dialog intelligibility

- wide dynamic range with extremely low distortion

- well-matched timbre (tonal balance) between front speakers and surrounds

- precise localization of specific sounds (as in special effects)

- envelopment by ambient soundfield (without any localization of individual speakers to
distract from the action on-screen

- superb performance with musical sources

The unsurpassed quality of your M&K Home THX Audio speaker system means that all of
the excitement and emotional involvement of films and music will be brought to life in your home.
Turn down the lights, and let the experience begin!
