2. INTRODUCTION
Congratulations! Your new M&K THX Select
®
subwoofer truly represents the state-of-the-art in
subwoofer performance. The new dimension of deep and powerful bass it provides will both thrill and
excite you.
We strongly encourage you to read this owner's manual, as there is a great deal of information
provided here to help you get the best possible performance.
If you have any questions about your subwoofer, please contact your M&K Home THX
Audio dealer,
or call the M&K factory directly at (310) 204-2854, from 8:30 AM to 5:00 PM Pacific Time. We will be
more than happy to help you with any question, no matter how simple or complex it may be.
For more details on the installation and calibration of your Home THX Audio system, please refer
to the THX Installation & Operation Manual.
THIS OWNER'S MANUAL HAS TWO SETS OF SET-UP INSTRUCTIONS.
ONE SET IS FOR USING THE SUBWOOFER WITH A THX CONTROLLER.
THE OTHER SET IS FOR USE WITH NON-THX PROCESSORS.
To operate it with a THX controller, see Section 4 on Page 5.
To use it with a non-THX controller, see Section 6 on Page 8.
3. WHERE TO PLACE YOUR SUBWOOFER
M&K Subwoofers perform well in most room locations. Unless your ear is a foot or two away from
the Subwoofer, you will hear the deep bass coming exclusively from your Satellite (or main) speakers.
There is no need to place your Subwoofer in-between the Satellite speakers.
For the best performance, we recommend that your subwoofer be placed against a wall,
preferably in a corner.
The ideal place for the subwoofer is the corner with the best structural strength. If the corners are
roughly equal in construction, use the corner nearest the listening position. If the listening position is
in the front half of the room, place the subwoofer in a front corner. If the listening position is in the back
of the room, place the subwoofer in a back corner.
Feel free to experiment with the orientation of the subwoofer cabinet. Sometimes the best sound
results from aiming the subwoofer's front driver directly into the wall (1" to 2" from the wall itself).
If possible, avoid corners near doorways or openings.
Another option to find the best location for the subwoofer 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.
If you are using multiple subwoofers, 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. Try to
place multiple subwoofers at equal distances from the listening position to avoid phase cancellation.
