1. INTRODUCTION Congratulations! Y our new M&K THX speaker system will give you years of unmatched enjoyment and excitement while listening to your favorite musical and audio/video sources. We encourage you to read this owner’s manual, as there is a great deal of information provided here to help you get the best possible performance.
The S-150 and S-250 speakers are magnetically shielded. This means that they can be placed close to a television monitor without distorting the picture. If you place the speaker directly on top of a large screen direct-view monitor , there is some slight possibility of picture distortion.
A. HEIGHT (OR ANGLE) The S-250, and S-150 have a controlled vertical radiation pattern that makes the speaker ’ s location critical. It is very important to aim the tweeters at the main listening position in order to achieve their very best sound quality and their flat- test frequency response.
cially in the phantom center . Y ou may also want to angle (or "toe-in") the speakers slightly . This often improves the sharp- ness of the stereo image, and provides a wider seating area. The S-150 Left and Right speakers provide a default toe- in through the angle of their front baffles.
ets, or speaker hangers to make this easy to accomplish. Remember that they are designed to be installed verti- cally , with the tweeters aimed at the listeners' ears. They can, however , be placed at virtually any height. This includes sitting directly on the floor , tilted up, as well as being mounted at ceiling height and tilted down.
8. SA TELLITE/SUBWOOFER PHASING TEST In any system using a subwoofer separate from Satellite speakers, a phasing test must be performed to insure good bass blending. This test insures optimum sound in the critical bass frequencies where your Subwoofer and Satellite speakers overlap.
When tone controls or equalizers are used to boost frequencies, the problem occurs much more rapidly . Even a small boost of low or high frequencies can easily double the power requirement and lead to amplifier clipping at moder- ate levels.
12. CABINET MAINTENANCE The S-150's and S-250’s painted black finish does not require any special maintenance; regular dusting with a lint- free cloth and periodic cleaning is all that is required. Matching black paint can be used if necessary to repair any sur- face damage.
