Unpacking the System

Carefully unpack the speakers. If there is any sign of damage from transit, report it immediately to your dealer or delivery service. Retain the shipping carton and packing materials for future use.

Grilles

The cloth grilles should remain on the speaker during normal use. However, to remove a grille, use your fingers to carefully pry the top edge of the grille away from the cabinet so you can insert your fingers between the grille and the cabinet. Then slide your fingers down the inside of the grille frame from top to bottom which will cause the grille to pop free. The grille is NOT designed to be removed by only pulling on one side. The pins that hold the grille can be damaged. Also, do not use any objects other than your fingers to remove the grille as the finish or grille may be damaged. Be careful to keep rings, watches and other sharp objects from scratching the finish or tearing the grille cloth.

To replace the grille, carefully align the two pins at the top of the grille with their corresponding grommets and gently push them in until the grille is supported by the grommets. Then work your way down the grille gently pushing the grille pins into the grommets evenly until the grille is fully seated. Be careful to align the pins with the grommets so the cabinet, grille pins and grommets are not damaged. Also, take care to support the speaker so it does not tip over or fall off its mounting location while the grille is being removed or replaced. MCenter Note: The same grille removal and replacement procedures apply to the MCenter except you will begin at the left or right side and work towards the opposite side. MSubwoofer Note: The MSubwoofer grille is not removable.

Feet & Spikes

The M350, M340 and M250 come with rubber feet installed at the factory which are ideal for hardwood floors. Spikes are also included for placement on a carpeted surface. To install the spikes, carefully lay the speaker on its back on a soft, debris-free surface and remove the rubber feet by hand turning them counter-clockwise. Thread the spikes by hand to make sure they are inserted properly. Save the rubber feet for future use.

The M25, MCenter, and MSurround come with rubber stand-offs that are designed to be attached to the bottom of the loudspeaker when stand, shelf or cabinet mounting. This will minimize the vibration transferred from the loudspeaker to the stand, shelf or cabinet. It will also help to protect the finish of the loudspeaker and the mounting location. The MSubwoofer comes with rubber feet installed at the factory.

MSurround Note: It is recommended to mount the rubber stand-offs on the back of the side panels of the MSurround if it is going to be wall mounted. This will minimize the amount of vibration that is transferred directly to the wall. You may need to adjust the depth of the mounting screws to help ensure that the speaker is not mounted too loosely or too tightly.
