[. . . ] In some cases, the difference will be just enough so that the output from the Subwoofer arrives out of phase with the output of the Satellites. When this happens, that critical mid-bass is actually cancelled. You should re-do this test any time you move your speakers. powered subwoofers page 10 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 midbass 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. [. . . ] If the component has a digital input, and you are using a source component with a digital output, always use the digital input, not the analog input. B. C. You can take a measurement at the listening position to establish the reference level, but it is usually more accurate to take levels at about one meter from each speaker. Set all channels to exactly the same level. Point it directly at the speaker being measured. [. . . ]
