Placement 9
Generally, subwoofers have the most output when placed
in the corner of a room. However, this can also exagger-
ate the subwoofers output making blending difficult. We
recommend starting by placing the CW10 in a corner.
If, after the full range of tuning techniques have been
employed, the subwoofer sounds like it has too much upper
bass energy try pulling it away from the wall, toward the
listening position. This will lessen the reinforcement of these
problematic frequencies from the wall and likely smooth out
the response. Repeat the tuning techniques with the woofer
controls after you move it (see figure 6).
Ask Your Dealer
Your MartinLogan dealer can suggest many options for
optimal subwoofer placement. They also have many tools
at their disposal, such as experience, familiarity with the
associated equipment, and even sound analysis equipment
which may make the task of determining optimal subwoofer
placement easier.
Enjoy Yourself
The CW10 is a very refined subwoofer and will benefit
from care in setup. With the above placement tips in mind
you will find, over months of listening, that small changes
can result in measurable differences. As you live with your
subwoofer, do not be afraid to experiment with positioning
until you find the optimal relationship between your room,
settings and subwoofer that gives you the best results. Your
efforts will be rewarded.
Installing in a Cabinet
When placing the CW10 inside of a cabinet it is recom-
mended that there be a minimum of three inches of open
space between the cabinet and the front and back sides
(see figure 7).
