In these cases, please contact M&K Service and Parts department at (818) 701-7010, and we will send, at no
charge, replacement self-adhesive foam pieces that can be easily applied to the cabinet's front baffle. See
Figure 7 below. This will replace the foam normally held in place by the speaker grille and will insure that you get
maximum performance from your S-5000s.
9. SATELLITE/SUBWOOFER PHASING TEST
In any system using a subwoofer separate from Satellite speakers, a phasing test must be performed to insure
good bass blending. This test insures optimum sound in the critical bass frequencies where your Subwoofer and
Satellite speakers overlap.
HOME THX AUDIO SYSTEM
For a Home THX Audio system, follow the system instructions provided with the THX controller, as you will
need to have correct phase among all the speakers in the system.These instructions will take you through the front
channels, surround channels, and subwoofer.
SATELLITE/SUBWOOFER SYSTEM
If you own an M&K Powered Subwoofer, see its owner's manual for the correct procedure for matching phase
between the Satellites and Subwoofer. Its "SUBWOOFER PHASE" switch makes this important test very easy. If
your subwoofer does not have a "SUBWOOFER PHASE" switch, follow this procedure:
Play a familiar CD, LP, or tape with steady, consistent bass content through your system. Listen carefully to the
"mid-bass" region of 75 - 125 Hz.This is the part of the spectrum where electric or string basses and drums pre-
dominate. Then, reverse the Positive and Negative speaker inputs on the back of BOTH Satellite speakers.
You can do this at the back of both Satellite speakers, or at the Subwoofer's "TO SPEAKERS" terminals
(certain models only), but never at both locations.The lead that was on the Positive (+) terminal should be switched
to the Negative (—) terminal, and vice versa.
Now listen to the same musical passage as you did earlier, concentrating on the mid-bass region. If you hear
less bass, the original connections were correct. If you hear more bass, the new connections are correct.
You need to perform this test because when Satellite speakers are located separate from a Subwoofer, each
speaker is at a different distance from your ear. In some cases, the difference will be just enough so that the
output from the Subwoofer arrives out of phase with the output of the Satellites. When this happens, that critical
mid-bass is actually cancelled. You should re-do this test any time you move your speakers.
If you want to experiment further, you can move the Satellite speakers either towards or away from your
listening position, making changes in small increments. This will "focus" the system's sound to its optimum. When
you hear the best balance between stereo image localization and maximum impact and output in the mid-bass,
you have the ideal location.
