NOTE:

For the S-250, locate the speakers away from reflecting surfaces

near to the

sides

of the speaker cabinet. This includes side walls, the sides of

entertainment centers, other furniture, etc. The S-250 will sound and perform at its optimum level when mounted to M&K speaker stands and located out in the room.

C. SEPARATION BETWEEN LEFT AND RIGHT SPEAKERS

Here is a formula for achieving the ideal left to right stereo imaging. Think of a triangle formed by the locations of the left and right speakers and your listening position. Ideally, the subtended angle formed should be between 45 and 50 degrees. Roughly, this means that the left and right speakers should be separated by about the same distance that you are sitting back from the speakers. In other words, if the distance from your listening position to the point directly between the speakers is 10 feet, place the speakers so their centers are about 10 feet apart. See Figure 2.

The length of line A - B should be about the same as the length of line X - Y. (They may not seem to be the same in this diagram due to an optical illusion).

Line X - Y should equal line A - B.

(Line A - B appears longer in this diagram due to an optical illusion).

Try to follow the formula as close as you can. You can fine tune the placement by listening to a source with an image (such as a vocalist) centered between the speakers. When listening in stereo (no Center Channel speaker), move the speakers closer together or farther apart in small increments until you hear the sharpest an most cohesive image, especially in the phantom center. You may also want to angle (or "toe-in") the speakers slightly. This often improves the sharpness 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.

D. VERTICAL ORIENTATION

The performance of your speakers is dependent on their orientation. THX speakers are designed for controlled vertical dispersion and wide horizontal dispersion. By controlling the vertical dispersion, we limit the amount of sound that would otherwise be reflected with a time delay from the floor and ceiling (for the reasons discussed in B. above).

This means the speakers should always be vertically oriented. The S-150 is vertically oriented when its tweeters are vertically stacked (not next to each other). When vertical, the controlled dispersion is in the correct plane. If they are oriented horizontally (on their sides), listeners right or left of a direct line from the center of the speaker will hear a compromised sound quality, an irregular frequency response, as well as some other problems.

While this may be acceptable for background listening, we strongly recommend that you do not place them on their sides for any other listening. The S-5000,S-250 and S-150 must be oriented vertically (tweeters in a vertical line). See Figure 3-A(S-5000) and Figure 3-B(S-150 & S-250).

S-150THX AC, S-250 S-150THX specifications

MK Sound has established a formidable reputation in the audio industry, particularly for its commitment to high-performance surround sound systems. Central to their lineup are the S-250 and S-150THX speakers, designed to deliver exceptional audio fidelity and experience in home theater environments.

The MK Sound S-250 is a powerful subwoofer that emphasizes low-frequency performance, capable of producing deep bass effects that enhance the realism of movie soundtracks and music alike. With a robust 12-inch driver and high-efficiency amplifier, the S-250 can deliver 250 watts of power, ensuring that even the most demanding soundtracks are handled with ease. Its sealed, acoustically inert enclosure minimizes distortion, allowing for precise bass response that complements the overall soundstage without overpowering midrange or treble frequencies.

The S-150THX and S-150THX AC speakers are THX-certified surround speakers, ensuring they meet the rigorous standards established by Lucasfilm. The S-150THX features a 5.25-inch midrange driver and a 1-inch tweeter, arranged in a carefully designed enclosure that supports both direct and diffuse sound dispersion. This design enhances imaging and localization in multi-channel audio settings, making it ideal for immersive surround sound experiences. The S-150THX AC, which features an advanced amplifier and additional connectivity options, maintains the same commitment to high-performance audio with added flexibility for modern home theater setups.

Both the S-150THX and S-150THX AC incorporate MK Sound's proprietary technologies, including optimized driver phase response and sophisticated crossover networks. These technologies work together to ensure that sound reproduction is accurate and coherent across all frequencies, providing listeners with a true representation of the original audio source. Additionally, the speakers' carefully constructed enclosures help to eliminate unwanted resonance, further enhancing sound clarity.

In summary, the MK Sound S-250 and S-150THX series speakers are engineered for those who demand superb sound quality in their home entertainment systems. With features like robust power handling, THX certification, and advanced construction technologies, these speakers deliver an unparalleled listening experience that captures the essence of both music and film soundtracks. Whether for a dedicated home theater or a multi-purpose media room, MK Sound's offerings are designed to impress and satisfy even the most discerning audiophiles.
