2. 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,
as applied by M&K's engineering team, 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!

3. PLACEMENT OF YOUR M&K SPEAKERS

Your S-150 speakers can be installed in a wide variety of locations. They can be placed on stands, shelves, or book­cases, or more permanently mounted using brackets, direct attachment to the wall, or a ceiling suspension system. We
recommend placing the S-250 speaker either on stands or wall brackets, away from side reflective surfaces.

Your speakers have threaded mounting hardware permanently mounted into the cabinet in different locations on the
speaker's back baffle. These allow you to mount the speakers in a wide variety of locations, and to orient them for the
best possible sound. This hardware is 1/4 - 20, meaning 1/4 inch in diameter, and 20 threads per inch.

There is a four hole mounting pattern on the rear baffle to accommodate either a M&K ST-series wall mount brack­et or ST-series component speaker stands.

You can place your speakers virtually anywhere in the room, but certain locations are better than others. In gener­al, locate them away from obstructions that would interfere with the direct path from the speakers to your ears (such as
walls, furniture, lighting, plants, etc.). They will sound better when they are around ear height, or when angled towards
your favorite listening location. Proper speaker alignment will assure optimal speaker performance.
