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 Depth 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 Depth 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.

corner placement of the Depth i at the front of the listening room.

 Placing the Depth in a cabinet requires a minimum of three 

inches of open space on the front, left and right.
