Protect Your Investment
• Use an amp that approximately matches the speaker's specified power handling.
• To avoid damage, turn down the volume if the speaker sounds like it is distorting,
sounds harsh, or the bass begins to break up.
• Tone controls and equalizers may increase the likelihood of distortion, especially at
high volumes. Use these settings sparingly.
Break-In
When you first begin to play your speakers, they will sound a bit bass shy. This is due
to the high quality, long-life components used in the drivers. Allow approximately 72
hours of break-in at 90dB (moderate listening levels) before any critical listening.
General Speaker Placement
Choosing a Mounting Location
Install the speakers between wall studs or ceiling joists being careful to avoid electrical
wires behind the wall's surface. Please note, ML-67i should only be used in-ceiling.
Wall Rigidity Results in Better Sound
Increasing the rigidity of your walls may improve sonic performance. To do this con-
sider adding cross bracing inside of the wall approximately 12-inch (30cm) above and
below the speaker.
Achieving Superior Imaging
These MartinLogan in-wall and in-ceiling speakers offer superb imaging and flexible
placement in nearly any location. However, for best performance and imaging place
speakers equidistant from one another and avoid physical obstructions between the
speaker and primary listening position.
Balancing Hard vs. Soft Surfaces Improves High- and Mid-Frequency Performance
Rooms that are “over damped” with carpeting, drapes, and other sound absorbers can
cause your system to sound dull and lifeless. On the other hand, rooms can have so
many hard surfaces that the system sounds like a gymnasium. Experiment by adding or
removing soft surfaces until you find a mix that sounds good to you.
Balancing Bass Output
Corner placement of these speakers will reinforce their bass output. If you require bal-
anced output across the entire audio spectrum avoid mounting these speakers in a corner.
