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 con­sider 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 bal­anced output across the entire audio spectrum avoid mounting these speakers in a corner.

6

When choosing placement follow these simple tips:

• Place a minimum of 12-inches (30cm) from any wall corner.

• Place fronts/centers equidistant between 10–14 feet (3–4.3m) from the listening position.

• ML-67i: Install in-ceiling only.

Placement Options (ML-60, ML-65i, ML-66i, ML-80i)

Stereo and Home Theater Applications (no illustration)

MartinLogan Installer Series in-wall and in-ceiling speakers are ideal for 2-channel stereo
and multi-channel home theater installations. The guidelines from the previous section
apply to both in-wall and in-ceiling speakers.

Multiple Speakers, Distributed Audio (Fig. 1a)

In larger areas (offices, etc.) multiple speakers may be used to eliminate the sound
imbalances that occur with separate stereo speakers as people move around the room,
or are seated closer to one speaker than the other. Position speakers to achieve the
broadest sound coverage in the main listening area.

Placement Options (ML-62i Stereo Speaker)

ML-62i speaker offers two options for connection to an amplifier:

• 2-channels from a single speaker (2 amp channels connected to the speaker)

• 1-channel with wide dispersion (bridged for mono, 1 amp channel conencted).

2-Channel Sound From a Single Speaker (Fig. 2a)

Ideal in smaller areas a single speaker is the preferred choice. The ML-62i is connected
to the amp's left and right channels. Position the speaker to achieve the broadest sound
coverage in the main listening area. Connect left and right channels to the speaker.

5.1-Channel Wide Dispersion Surround Placement Using Two Speakers (Fig. 2b)

Place an ML-62i on either side of the listening area. Orient so one tweeter points toward
the front of the room and the other points toward the back. Bridge each speaker for mono
and connect the amp's left and right surround channels to the appropriate speakers.

6.1-Channel Wide Dispersion Rear Placement Using One Speaker (Fig. 2c)

Center one ML-62i behind the listening area, tweeters pointed toward the left and right
of the room. Bridge the speaker for mono and connect the amp's rear channel.

7.1-Channel Surround + Rear Placement Using Two Speakers (Fig. 2d)

Place one ML-62i on either side of the listening area. Orient so one tweeter of each

speaker points toward the front of the room and the other points toward the back.
Connect the amp's left and right surround and rear channels to the appropriate speakers.

7.1-Channel Rear Placement Using One Speaker (Fig. 2e)

Center one ML-62i behind the listening area with tweeters positioned toward the left and
right sides of the room. Connect the amp's left and right rear channels to the speaker.

Placement Options (Aimable ML-67i Speaker)

ML-67i speakers are optimized for use in rooms with ceiling heights ranging from 8–9
feet (2.4–2.74m). Point the tweeters toward the primary listening position. For overall
clarity and balanced bass performance, these speakers should be mounted in the ceiling
12 inches (30 cm) or more from the wall, as shown in Figs. 3a to 3f.

Left/Center/Right Placement (Fig. 3a & 3b)

Follow the general guidelines for speaker placement provided at the beginning of
the main section keeping in mind the distance from the front speakers to your primary
listening area should be 10–14 feet (3–4.3m), as shown. Point the drivers toward the
primary listening position.

Non-Direct Radiating Surround/Rear Placement

These speakers are also ideal for use as surrounds and rears. Aiming the speaker so sound
bounces off the walls creates an enveloping, reverberant sound field. Keep in mind that
speakers should be mounted 12 inches (30 cm) or more from the wall.

•

5.1-Channel Surround Placement (Fig. 3c): Position one speaker on either side of the

listening area, with drivers pointed toward the side walls.

•

6.1-Channel Rear Placement (Fig. 3d): Begin with ‘5.1-Channel Surround Placement’ (above).

Center one speaker behind the listening area with drivers pointed toward the back wall.

•

7.1-Channel Rear Placement (Fig. 3e): Begin with ‘5.1-Channel Surround Placement’

(above). Position another pair of ML-80i speakers behind the listening area, one slightly to
the right, the other slightly to the left, with drivers pointed to the back of the room as shown.

Direct Radiating Surround/Rear Center Placement (Fig. 3f)

The ML-67i may be used as direct-radiating speakers, positioned with drivers pointed
toward the listening area. Use Fig. 3f as a guide to positioning as you experiment to
achieve optimal surround sound in your room.

Installation

NOTE: These instructions assume the mounting surface is of standard wood frame and
standard sheet rock construction. If you wish to mount the speakers to another type of
material you should contact a bonded contractor.

NOTE: See your local dealer for new construction pre-install brackets (sold separately).

NOTE: While it is possible to use a manual screwdriver for installation, we strongly sug-

gest using a power drill. To avoid damaging or breaking the clamps, set your drill to a
LOW setting. A high power setting is NOT necessary and may cause clamps to crack or
break from the added force. Such damage is not covered under warranty.

WARNING! Before installing check local building codes to verify com­pliance with local regulations. WARNING! Before installing check for
obstructions behind drywall. To do this make a small hole, cutting at
a 45° angle (this will make the hole easier to patch if obstructions are
found). Only cut out the mounting hole after you have verified there are
no obstructions behind the dry wall. WARNING! Use only speaker cable
that is rated for in-wall use. The UL standard is CL2, CL3, and CM. The
CSA standard is FT4. WARNING! Turn your amplifier off before making
or breaking any signal connections.

Recommended tools:

• Stud finder

• Sharp pencil or pen

• Dry wall knife/saw

• Wire strippers

• Power drill with
Phillips screwdriver

• Tape measure

• Low-tack tape

1. If the template has a removable center, remove it at this time.

2. Using a stud finder, position the template completely between wall studs or ceiling

joists. ML-67i: Install in-ceiling only.

3. Hold or tape the template in place and mark cutout with a pencil. For rectangular

speakers, level the template before marking (Figs. 5a, 6a.1, & 6a.2).

4. Remove the template and cut out the opening with a drywall knife (Figs. 5b & 6b).

5. In-wall: Place fiberglass insulation above and below the cut-out hole. Place a half

thick piece of fiberglass insulation behind the speaker. In-ceiling: Place fiberglass
insulation 12" (30cm) or thicker between the joists directly above the speaker.
