The overall system is expected to reproduce frequencies at the entire bandwidth, but as the subwoofer will be rolling off
above the crossover point, it is therefore recommended to look at the main speakers or satellite speaker’s specification
sheet for frequency response, in order to choose the best working crossover frequency at subwoofer.
Setting the sub woofer crossover control to the same frequency as the lowest given value for a main speaker or satellite
speaker, is a good start setting. The satellites, or main speakers, which reproduce the upper frequencies, need only 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 M&K 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 4WHERE 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 phono subwoofer output, you may need to use a “Y” connector to feed
the additional subwoofers.
10. HOME THEATER USAGE
The subwoofer in a home theater system has a critical role to play in the enjoyment of your system, which makes perfect
sense, as the subwoofer is the only speaker in your system capable of accurately reproducing low bass.
All the bass from the main channels is reproduced by the subwoofer, including Low Frequency Effects (LFE) that creates
the dramatic low end frequencies we hear in movies. In the electronics bass management setup, a choice of large speaker”
mode or “small speaker mode will appear. Your M&K subwoofer is designed to operate in both modes, and the choice of
large / small speakers is concern of size for satellites only.
In either setting, make sure you have connected the “line level Phono subwoofer output” from your home theater receiver or
processor, to the line level Phono input on your subwoofer.
Make a final check of your receiver or processor that subwoofer is selected as “On” or “Yes” in the setup menu, to ensure all
low frequency material from your receiver or processor, and sent to your subwoofer through this connection.
The routing of signals for satellites and subwoofer is internally distributed to the 5.1 or 7.1 system by the surround receiver
or processor build in bass management system, where the .1 is referring to the subwoofer output channel. In cases where a
setup with multiple subwoofers is wanted, it will still be the receiver or processor .1 output that will drive the added numbers
of subwoofers.
NOTE: For maximum enjoyment of your M&K Sound satellite/subwoofer system, we recommend to set your
Receiver or processor to “Small” for speakers.
