Unpacking and Handling
The F300, especially the bass unit (F300S), is both heavy and relatively
delicate and must be handled with care. When moving the speaker still
in the cardboard box, gentle rolling is generally allowed. But dropping
from any height should absolutely be avoided. It is preferable to unpack
the speakers close to the position at which they are to be used.
Fig. 1 illustrates two alternative ways to take the speaker out of the box.
After taking out the speaker, please also take out the foam at the bottom
as accessories are placed in the concave spaces of the foam.
Speaker Placement
The speakers should be placed 7 to 9 feet apart (measured between
nearest sides) for a natural sound stage. Too far apart, while focus still
maintains, the sound stage may become artificially wide. An ideal
listener to speaker distance should be that the two speakers and the
listener are at three corners of an equilateral triangle. Ideally, the speak-
ers should be at least 2 feet away from the back and side walls. Moving
the speakers further from the walls will generally reduce the volume of
bass. Space behind the speakers will also help to expend depth of the
sound stage. Because of the uniform sound dispersion of an air motion
transformer (AMT) tweeter employed by the F300, distance to the side
wall is not as critical as that of dome tweeter speakers. For the same
reason, toe-in (speakers pointing at the listener) is generally not
needed, in fact, not preferred as less toe-in may fill the room better.
Most room treatment experiences are developed based on the widely
used dome tweeter which beams sound and tends to have problems
with rooms. Because the F300’s AMT tweeter, which is a dramatic depar-
ture from traditional dome tweeters, has a wide and uniform horizontal
dispersion pattern, the F300 is less affected by the room, and placement
is relatively more forgiving. However, since the F300 produces substan-
tial amount of bass, bass traps, especially at the corners, can often
