In some cases, however, you may prefer the subwoofer set to a higher playback level for video
sources. This may occur when video sources (especially older films and some television) have very
little deep bass present. You may also want to exaggerate the effect to make spectacular video sources
even more impressive!
When your subwoofer is going to be located close to a television set, remember to leave 2 - 3 feet
of clearance between the television and subwoofer, unless the subwoofer is magnetically shielded
(V-125, MX-1000 and MX-1000cc only).
CONNECTING THE SUBWOOFER TO A SURROUND
SOUND RECEIVER OR PROCESSOR:
The preferred connection from a surround sound amp or controller is from a SUBWOOFER
OUTPUT RCA jack. This connection usually insures that a full bass signal is fed to the subwoofer. If
your component doesn't have a subwoofer output jack, connect the Subwoofer to the front Left and
Right channel speaker outputs (don't use the Center channel).
VERY IMPORTANT: When the Subwoofer is connected to the Left and Right amplifier outputs
(this means using speaker wires), and the controller is in Pro-Logic mode, the Center channel WIDE/
NORMAL switch MUST be set to the NORMAL mode. If the switch is set to the WIDE mode, the bass
content of the Center channel will not be fed to the Subwoofer, and a significant amount of the bass
in the material you are listening to will be lost.
10. SPECIAL INSTALLATION NOTES
MX-2000, MX-100, MX-90, MX-80, V-100, V-90:
An enclosed hardware kit contains four black metal spikes, threaded at one end and tapering to
a sharp point at the other. Depending on their orientation, they can be used either as spikes or rubber
feet. Do not use the spiked feet on hardwood or tile floors. They can damage the floor surface.
By mounting these spikes into the threaded inserts mounted in the bottom of the Subwoofer, you
can elevate the Subwoofer, and on carpet, couple it more tightly to that floor. On hardwood, tile, or
concrete, the spikes should be inverted, with the point mounted facing into the cabinet. One of the black
rubber feet provided should then be pressed over the exposed flat end of the foot.
The threaded inserts are found in the four corners of the cabinet's bottom. The MX-2000 has a
fifth insert, which allows you to use three of the five in a triangular pattern. The inserts are 1/4 - 20,
that is, 1/4 inch in diameter and 20 threads per inch. This is compatible with the most spikes, "cones,"
"tip-toes," etc. offered by other manufacturers.
To properly secure the feet to the cabinet, you must use the provided washer and jamb nut on the
threaded portion of the foot. The washer goes first, with the nut over it, holding the washer securely
in place. This prevents damage to the spike and insert if something moves the cabinet sideways.
MX-100, MX-90, MX-80, MX-70:
Because your M&K MX-series Subwoofer uses an "inverted" driver that fires down into the floor,
it loads differently to the room than a conventional speaker or forward-firing Subwoofer. This means
that you may want to experiment a bit more with its placement and setup to get optimum sound quality.
