Magnepan MG .7 - Manual (Page 7)

12 Phasing
To realize the optimum phasing, the .7 should be angled inward as shown in
the diagrams above. (Do not place parallel to the front wall.) For a larger
"sweet spot" and multiple listeners, place tweeters on the outside. Single
listeners may choose to place the tweeters on the inside. If you do, cant the
speakers inward sufficiently so that the tweeter is not ahead of the bass/
midrange in time as shown in the diagrams above.
13 Room Acoustics
The judicious use of damping material can improve the sound. Acoustical
damping can be achieved with household items or wall hangings. A word of
caution--when audiophiles discover the effectiveness of damping material,
they sometimes overdo it (on the premise that if a little is good, more is
better). Before making a permanent change to your room, experiment with the
positioning of the damping material. Usually a portion of one or two parallel
walls should have some damping. However, it is a trial-and-error process.
An over-damped room will provide very precise imaging, but the sound will
seem "dead." An under-damped room may heighten the illusion of being in a
concert hall, but the imaging will seem imprecise with all the instruments
mixed together. "Hardness" or over-bright sound is usually the result of a room
with hard surfaces (glass, hard paneling,etc.). Moderation is the key.
Diffusers are also helpful to improve the acoustics of a room. Contact your
Magnepan dealer for more information on the proper use of diffusers.
14 Optional Tweeter Attenuation
There are two principal reasons for needing to attenuate the Magneplanar
Quasi-Ribbon Tweeter and Super Tweeter:
A. Pop or rock recordings often exhibit a pronounced rise in the treble
region.
B. The Magneplanar Quasi Ribbon Tweeter is very efficient in its total energy
dispersion. If the surrounding walls are exceptionally reflective, the overall
perceived acoustical balance will be tipped towards a "hot" high end.
