Again, it’s only necessary to reduce the reflectiveness of one of the surfaces in each pair of surfaces to
eliminate flutter echo. Since this concerns the high frequencies, any soft material is appropriate.
Drapery or fabric wall hangings are quite effective on the walls. Bookshelves also work well by
breaking up the flat surfaces. Carpeting should eliminate potential problems between the floor and
ceiling.
Additionally, it is desirable to maintain a degree of left/right symmetry in the room to preserve a
balanced acoustic “space”. For example, if your listening room has full length draperies along the
right wall, and the left wall is bare, slap echo will not be a problem. Nonetheless, the sound stage may
be somewhat distorted, and it could be beneficial to place a fabric or tapestry on the wall opposite the
draperies.
Improve sound dispersion in the room
Speaker placement relative to the floor and walls can affect a uniform dispersion of sound in the room. Similar
to the way that mirror reflects the light of a light source, so can the surfaces near the loudspeaker reflect the
sound waves back into the listening room. There are typically three reflective surfaces near each speaker: the
floor, the rear wall, and the side wall. Each of these surfaces produces its own reflections, and hence its own
cancellation and reinforcement, as well as changes in sound dispersion. By properly selecting the distances to
each surface, we can provide a more uniform sound dispersion. Conversely, improper placement of the
loudspeakers can result in uneven frequency response and lower sound quality.
Your Magus speakers have a unique capability to improve sound dispersion in the room when used with
dedicated Magus stands. The Magus stands are equipped with an adjustable plate (reflector plate) that allows
changes in distance between the port at the bottom of the speaker and the reflector plate.
Adjusting the reflector plate in the range of 1.5 inch to 12 inches below the port will change sound
dispersion to allow room imperfections to be compensated for – relative to the position of speakers in
the room. This mostly takes effect in the range of approximately 250 Hz to 2,000 Hz.
IMPORTANT NOTE: distance between the port and the reflector plate
must
be at least 1.5 inch or
more, otherwise the airflow from the port will be obstructed and the speaker may not function
properly!
