Maintenance Precautions - Fostex NX-5A Owner's Manual

Adopting the time alignment construction, as well as mounting the woofer and tweeter closely, the NX-5A
provides a wide monitoring area.
We recommend to install the NX-5As vertically, as shown below, not only from the point of view of audio
phase characteristics but also from the point of view of radiation of the built-in power amplifier. As a hu-
man ear is sensitive in the left-right direction, setting the unit horizontally is undesirable from the point of
view of phase characteristics.
• Optimal listening point and setting
To get the best of the NX-5A performance, set them at the appropriate height so that the middle point
between the center positions of the tweeter and woofer matches the listener's ear height.
Then, orient them 15 to 30 degrees inward to form a triangle as shown in the Figure below.
The vertex of the equilateral triangle in the Figure is best listening position.

Be careful when cleaning speaker/enclosure surfaces!!
• No protecting grilles or covers are provided with
NX-5A. Brush off dust attached to surfaces of
speakers with soft dusters. Avoid direct fingers or
damp dust cloth contact with diaphragms.
