Wiring With Line-Level Inputs - MK Sound MX350 MKII Operation Manual

We recommend that you place your subwoofer as close to a solid wall as possible. Avoid placing
your subwoofer farther than a few inches away from any wall surface as the reflected sound from
the wall will interfere with the direct sound coming /from the subwoofer and create phase
anomalies that will be destructive to good bass performance. Also try to avoid corners that are
near doorways or openings.
Sometimes the best sound results from aiming the subwoofer's drivers directly into the wall (1" to
2" away from the wall itself.)
If you are using multiple subwoofers, sometimes putting them in the same location provides the
best solution. Stacking them is also a possible solution or you could place them side-by-side.
Alternatively, when using multiple subwoofers, you could try placing them in different locations.
This may be appropriate when you have limited choices for placement and none of the available
locations seem to work well. Try to place your subwoofers at equal distances from the listening
position to avoid phase problems.
Ultimately, the amount and quality of deep bass you get in your room are dependent on the room
itself. Low frequency sounds are affected most by the size of the room and construction used to
build it. All rooms are different when it comes to reproducing bass, and in any given room, bass
quality and quantity change when the subwoofer is moved from one location to another.
In some rooms, a corner location may excite resonance modes resulting in a muddy or boomy
sound. In this situation, a more central location along a wall, away from a corner may give better
results. It's a good idea to experiment with your subwoofer location or locations. Try to find a
placement or placements that provide an overall sound that is powerful and well defined
throughout the audio bandwidth, where no one bass note or notes overpower others.
Because the subwoofer generates so much sonic energy, its output may cause objects in and
around the listening room to vibrate. If this occurs in your room, you may need to damp the
vibration of these objects.
One subwoofer is usually sufficient in a two-channel stereo system for the same reason that one
subwoofer works well with multi-channel systems. Our ear-brain hearing physiology is unable to
locate the direction of low frequencies below approximately 80 Hz. The directionality of low
frequency sounds (bass drums, bass instruments, etc.) is determined by the higher frequency
overtones and harmonics that are reproduced by the satellite speakers.
Some people believe that we can determine directionality from frequencies down to 60 Hz. In any
case, MK Sound satellite speakers are tuned to crossover to an MK Sound subwoofer at 80 Hz.
This is also the Dolby Laboratory and THX specification.
Your MK Sound subwoofer is magnetically shielded to eliminate adverse effects when a
subwoofer is placed next to a conventional CRT (cathode ray tube) television or computer. While
the new plasma and LCD screens should be immune to magnetic interference, some of the older
plasma screens experienced gausing (green shadows appearing on the screen) when a magnetic
source was placed next to it.
