7. “BYPASS” SETTING
All current home theater receivers and processors provide the necessary high-pass and low-
pass filtering (bass management) to ensure proper integration of satellite/subwoofer speaker
systems. When using your subwoofer with one of these components simply set the “LOW-PASS
FILTER” control on the back of the subwoofer to the “BYPASS” position. This bypasses the
subwoofer’s internal low-pass filter so that there is no interaction between the subwoofer’s filter
and your receiver or processor’s filter. This is the recommended setting for your subwoofer.
8. “LOW-PASS FILTER” CONTROL
If your receiver or processor does not have an internal crossover, there is another way to match
the subwoofer to your main speakers using the “LOW-PASS FILTER” control. This control sets
the upper roll-off point of the subwoofer and allows you to integrate your satellites with your
subwoofer so you can enjoy full audio bandwidth reproduction from 20 Hz to 20 kHz. The control
is a means of fine-tuning the transition of sound between your satellite, or main speakers, and
your subwoofer. It provides a roll-off of 12 dB/octave up to 200 Hz where the filter shifts to 36
dB/octave. In most systems, including MK Sound systems, 80 Hz gives the best blend.
The satellites, or main speakers, will reproduce frequencies from 80 Hz to 20 KHz and your
subwoofer will reproduce frequencies from 80 Hz down to 20 Hz.
Whether you use the bass management controller in your receiver or processor or the method
discussed here, this is the most efficient method of reproducing full bandwidth multi-channel
audio today.
The satellites, or main speakers, which reproduce the upper frequencies, need only a small
cabinet and small drivers to do their job, while the subwoofer, which reproduces the low
frequencies, requires a larger cabinet, a larger driver and sufficient power in order to do its job.
Properly tuned, your MK Sound satellite/subwoofer system will provide you with the highest
quality sound reproduction available today.
9. USING MULTIPLE SUBWOOFERS
Using two or more subwoofers in your system will give you the ultimate in low bass performance.
You will hear improved impact and definition, as well as greater output and dynamic range.
While all the information in section 4 WHERE TO PLACE YOUR SUBWOOFER should be
observed, additional considerations need to be taken into account when using multiple
subwoofers.
First, try to place all subwoofers at equal distances from the listening position. This will help to
avoid phase anomalies.
Check the phase relationship between each subwoofer and your main speakers by using the
phase test discussed earlier.
Since your receiver or processor may only have one XLR or phono subwoofer output, you may
need to use a “Y” connector to feed the additional subwoofers.
