MartinLogan Descent i [16/28] Listening position
![MartinLogan Descent i [16/28] Listening position](/views2/1197725/page16/bg10.png)
Listening Position
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 subwoofer in a corner.
It should be placed in such a way that there are 2 inches
between the grill and the wall. This will avoid blocking
the output of any woofers. 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 less-
en the reinforcement of these problematic frequencies
from the wall and likely smooth out the response. Repeat
the setup procedure with the woofer controls after you
move it (see figure 16).
Installing in a Cabinet
It is common for people to place their subwoofer(s)
inside of cabinetry. The Descent i’s unique, three-woofer
design does not compromise the ability to be successfully
installed in such a configuration. However, it is recom-
mended, as with any quality multi-driver subwoofer, that
there be a minimum of three inches of open space
between the cabinet and the front, left and right sides (see
figure 17).
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 equip-
ment which may make the task of determining optimal
subwoofer placement easier.
Enjoy Yourself
The Descent i 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 position-
ing until you find the optimal relationship between your
room, settings, and subwoofer that gives to you the best
results. Your efforts will be rewarded.
