If you want to experiment further, you can move the Satellite speakers either towards or away from your
listening position, making changes in small increments. This will focus the system's sound to its optimum. When
you hear the best balance between stereo image localization and maximum impact and output in the mid-bass,
you have the ideal location.
6. USE OF THE "LOW PASS FILTER" CONTROL
The back panel control "LOW PASS FILTER" sets the upper rolloff point of the Subwoofer, eliminating mid-
bass and midrange that are being reproduced by your Satellite speakers. The control is a means of fine-tuning
the transition between your Subwoofer and Satellite speakers, and it provides a rolloff of 12 dB/octave up to 125
Hz, where the filter shifts to 36 dB/octave. In most systems, including M&K Satellites, 85 Hz gives the best blend.
If you don't want to experiment, set the control at 85 Hz. If you are using the K-5 / K-7 Satellites, set the control
to 100Hz. If you are using Xenon satellites (LCR45, LCR35, or LCR25) set the control between 100 and 125 Hz.
The goal is to get a balanced
acoustic
output in your room. This is not necessarily the same as flat electrical
output. Rooms typically reinforce bass frequencies around 100 Hz, so by leaving an electrical gap, you may
actually get a smooth acoustical response where it matters, in the room.
Think of this control as a mid-bass fine tuning adjustment that you set to achieve the best transition between
the Satellite speakers and the Subwoofer. When you hear a smooth sound overall, well balanced between the
deep bass and the rest of the audible spectrum, the control is set properly.
7. USE OF THE "BYPASS" SWITCH
If you have a THX, Dolby Digital, or DTS component with a built-in Low-Pass filter as part of its subwoofer
output, or if you are using a separate Electronic Crossover, set the “VARIABLE” / “BYPASS” switch on the back
of the subwoofer to “BYPASS” position. This bypasses the internal low-pass filter so that there is no interaction
between the subwoofer’s filter and your component’s filter. If you have any questions regarding the filters, please
contact your M&K dealer or the M&K factory.
8. USING MULTIPLE SUBWOOFERS
Using two (or more) subwoofers in your system gives you the ultimate in bass performance. You'll hear
improved impact and definition, as well as greater output and dynamic range.
If multiple subwoofers are used, place them in the same location. Stacking is best, but you can also put
them side by side. Alternately, you can put multiple subwoofers in different locations. This is appropriate when
you have limited choices in locating the subwoofer and none of the available locations work well. Try to place
multiple subwoofers at equal distances from the listening position to avoid phase cancellation.
With two Subwoofers, simply run one speaker wire or interconnect to each Subwoofer. Because the left
and right channel input signals are combined in the Subwoofer's input stage, the only thing this changes is
amplifier gain. To compensate, just set the "BASS LEVEL" control slightly higher.
9. K-11 POWERED SUBWOOFER
The K-11 subwoofer is a truly unique product, allowing K series enthusiasts and discerning listeners with
space constraints the flagship level of performance found in M&Ks MX series subwoofers
The K-11 is identical to the K-10 except that its 8" driver is mounted inverted. When a K-10 and a K-11 are
stacked or placed side-by-side, the combination produces a no-compromise, very high-quality push-pull dual
driver subwoofer package that fits just about anywhere.
