If it is in the back of the room, place the subwoofer in a back corner.
If possible, avoid corners near doorways or openings.
B.
If you are willing to experiment, another option is to place the subwoofer at the listening
position and walk around the room. Stand in and near each corner. The location where
you hear the tightest bass with the most impact is probably the best location in the room
for the subwoofer.
C.
If multiple subwoofers are used, place them in the same location. Stacking is best, but
you can also put them side by side.
Another option for multiple subwoofers is to place them 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.
3.
Locate the surrounds. Determine the best position in the room. It will probably be the position
used for THX speakers, directly to the right and left of the main listening position on the side walls (so that
a listener in the center seat is directly between the speakers). If that doesn’t work or is not practical
because of the room, try these locations: on the ceiling; on the back wall.
4.
Install all wiring and interconnects.
5.
Connect the subwoofer. Always use the processor/receiver’s subwoofer output.
6.
Aim the front left and right speakers in both the horizontal and vertical planes. Horizontal toe-in
helps to get the best possible imaging.
7.
If you have a Dolby Digital or DTS processor/receiver, follow these instructions. If you have a
Pro-Logic processor/receiver, go to item 8 below.
SPECIAL NOTE: Always check the processor/receiver’s owner’s manual. Different manufacturers use
different descriptions for the same function, and sometimes the same description for different functions!
Your component may use terminology different from that used below.
A.
High-Pass Filters: All Dolby Digital processor/receivers have built-in high-pass filters for
the Left, Center, Right, Left Surround, and Right Surround channels. Always turn these
filters ON by using the SMALL setting. If you have a THX component, use the THX
setting. See the owner’s manual of the processor/receiver for instructions.
B.
Bass Management: If the processor/receiver has a setting to turn the Subwoofer off or on,
make sure that it is set to SUBWOOFER YES or ON.
C.
Dialog Normalization: If your component has this function, turn it off to avoid any possible
effect on sound quality.
D.
THX Dolby Digital units have an adjustable limiter for the subwoofer feed, called “Bass
Peak Level Management”. Turn it off, or set it for the highest possible level.
M&K
subwoofers do not need this limiter.
8.
If you have a Pro-Logic only processor/receiver, follow these instructions.
SPECIAL NOTE: Always check the processor/receiver/receiver’s owner’s manual.
Different
manufacturers use different descriptions for the same function, and sometimes the same description for
different functions! Your component may use terminology different from that used below.
