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.
