With a little experience, one person can install an MMC 2. However, for the first time, it is

recommended that an assistant help with steps D and E of the installation.

A. SELECTION OF SPEAKER LOCATION

Before a permanent installation is begun, we highly recommend purchasing the $30 pair Disposable Speaker

Stand Kit to determine if the selected location gives the desired audio performance for the MMC 2s before the first

holes are drilled. These mobile wall stands allow the speakers to be easily moved around the room until a

permanent position is located. A set of mounting brackets are included with the MMC 2 speaker panels for

placement of the speaker panels on the Disposable Speaker Stands.

Because the MMC 2 can used for any channel in a home theater or music system (including as a center channel),

and because rooms conditions vary greatly, specific and detailed instructions are not practical. However, there are

general guidelines to follow.

Avoid corners. Choose a placement that will position the MMC 2 as far from a corner as possible - preferably

more than 3 or 4 feet and the further, the better. We want you to be a satisfied customer and this is a critical issue

for good sound. This is especially important for the front channels. Rear channels play a lesser role and more

liberties can be taken with the rear channels.

Choose a placement that will allow the bottom of the MMC 2 to be approximately 26 inches from the floor for proper

high frequency dispersion when you are sitting or standing.

To help determine the front of the MMC 2, the quasi ribbon foil can be seen through the fabric on the front of the

speaker. The speakers should be mounted so that the front of the speakers are on axis with the listener.

CAUTION- Using a level, check to see if the walls are within building code for plumb (vertical to a level floor). If the

walls are too far out of plumb, the speakers may not open or close.

B. PAINTING SPEAKER FRAMES

Many customers will want to paint the top and bottom molding to match their decor. The top and bottom frames can

be ordered with a primer coat. We recommend Krylon spray can paint.

1. Mask off hardware in the speaker frames to prevent paint from fouling mechanical parts. Using a very fine

steel wool or sandpaper, lightly sand the primer surface to remove any possible contaminants from oily

fingers, etc.

2. Spray 4 or 5 light coats, allowing drying time to prevent runs in the paint and for a smooth finish. Sand with

fine 600 sandpaper between coats for an extra-smooth finish.

3. Spray a coat of Krylon clear coat (gloss or satin) to protect the finish.

4. Install the speaker trim in the edge of the speaker with a rubber mallet. (Masking tape over the trim will help

4. Install the speaker trim in the edge of the speaker with a rubber mallet. (Masking tape over the trim will help prevent marring of the finish from the rubber mallet.) 5. Install 3/4 inch, 18 ga. brads in the speaker trim to secure the trim.

C. TIPS FROM THE PROS FOR DO-IT-YOURSELFERS 1. To run a speaker wire into a wall and out another hole at the bottom, insert a fine steel chain in the top hole that is the length needed to reach the junction box. Use a magnet at the junction box to locate the steel chain. The steel chain will be used to pull the speaker wires through the wall. 2. In some cases, it is not practical to route the wires in the wall. A hide-a-cord channel can be used to route the motor wires on the wall down to the lower frame.

D. TOP FRAME INSTALLATION 1. Thread motor wires through the 1/4" dia. center hole and attach the top frame using keyholes on the back of the top frame. If necessary, adjust the screw height to insure a snug fit of the top motor frame to the wall. See Fig. 3 & 4. Fig. 3 Fig.
PAGE 6
E. ATTACHING BOTTOM FRAME TO SPEAKER 1. Caution-- Do not rest the weight of the speaker panel on the speaker wires. Under extreme force, the steel tube could cut through the insulation. 2. Lay the speaker on a table with the bottom extending about 12" over the edge of the table. 3. Thread the speaker wires through the bottom frame and insert the bottom pin of the speaker into the pivot hole of the bottom frame. See Fig. 5 & 6. Fig. 5 Fig.

F. BOTTOM FRAME ATTACHMENT TO WALL 1. While keeping the bottom frame and speaker together, take the speaker to the wall for installation. See Fig. 7. 2. Feed the speaker wire through the 1/4" dia. bottom center hole and attach the lower frame to the wall using the keyholes on the back of the bottom frame. See Fig. 8 & 9. Fig. 7 Fig. 9 Fig.

G. FINAL SPEAKER INSTALLATION Many of the adjustments and installation are much easier with the aid of an LED headlamp. The final step is the most difficult (and may require the help of an assistant). Slightly raise the top frame to allow clearance for the pin on the top of the speaker wheel to clear the top frame when it will be moved into position. See Fig. 10. Slide the motor assembly (and drive wheel) back with your thumb (See Fig.

a file or Dremel tool to allow the frame to be lowered on one side. However, the head of the pan-head screw will impact on the interior portion of the frame. It is necessary to modify the screw with a file or grinder. First, make certain that the screw to be modified is adjusted to the correct amount to ensure a tight fit of the frame. Mark the top portion of the screw head with a permanent marker and remove the screw. Grind or file the marked portion of the screw and reinstall. I.

K. SPEAKER ANGLE ADJUSTMENT Some of the adjustments below are easier if the motor is pulled back using a strip of duct tape as described above in Final Speaker Installation. For the best sound, the MMC 2 should be angled so that the panel is on-axis with the listener with a minimum distance from the wall of 30 degrees. (Use of the MMC 2 as a dual center channel speaker requires slightly different adjustments. Contact Magnepan for dual center speaker installations).

the MMC 2. To ensure that the nylon screw will not loosen, wrap Teflon plumber's tape on the threads or a drop of blue Loctite or score the threads lengthwise. Fig.

Fig. 12 Fig. 13 Fig. 14 L. Phasing 1. Correct phasing between a "small" speaker, like the MMC 2, and the Bass Panel is much more difficult to detect than an out-of-phase condition between left and right speakers. The ear/brain is less sensitive to phase shift problems at lower frequencies and therefore, making it more difficult to detect. However, an out-ofphase condition between the MMC 2s and the Bass Panel will result in a perceived frequency imbalance.

phasing between the MMC 2s and your Bass Panel. The pink noise CD is "shaped" with a 9 db peak at 80-100 Hz. This aids in the detection of an out-of-phase condition. This peak in the midbass focuses the attention of the listener on this area of the frequency response. When the MMC 2s are out of phase with the Bass Panel, this peak will be reduced in level.
