JBL 4344 MKII User Manual

Ideally the systems should be placed at least three feet from any walls. The
height, at the bottom of the Lens assembly, should be at ear level. The two
speakers should be equidistant from your primary listening position; the
distance should be determined by the distance between the speakers. We
recommend that the angle between the speakers, at the listening position,
be between 45° to 60°. For example, if the speakers are 8' apart, your
listening position should be 8'–12' from each speaker. To widen the area in
which the best stereo image will be perceived, turn the speaker to face the
primary listening position (Figure 2).
It is normally recommended that the
4344MkII loudspeakers be
positioned so that the ultrahigh-frequency transducers are towards the out-
side. In some listening environments, however, the imaging characteristics
may be improved by positioning the ultrahigh-frequency transducers
towards the inside. We suggest you experiment with the positioning of
your loudspeakers to determine the ideal placement in your listening room.
