NHT Classic Four Setup Manual page 3

You will also notice an unusually shaped piece of foam
with an adhesive backing. The purpose of this foam is to
reduce unwanted reflections caused by interaction
between the tweeter and midrange drivers. To get the
best performance from the Three or Four, install this
foam part. Fig. 3 demonstrates where to mount the foam
part.

Placement
NHT's Classic Three can be placed on stands, on
shelves or hung on the wall. Given the high performance
of this model, NHT recommends placement on either
stands or on a shelf at close to ear level to achieve
maximum fidelity.
If you decide to wall mount the Three follow these simple
instructions. The model Three has threaded inserts on
the rear of the cabinet for wall mounting. NHT recom-
mends the use of OmniMount 20 series brackets. You
will need to purchase two, ¼-20 x 5/8" (length) pan head
machine screws to attach the bracket to the back of the
speaker. For

The model Four can be placed with the side-loaded
woofers pointing either inward towards each other or
outward. Choose the orientation that provides the most
free space around the woofer.
It is important to know that small changes in speaker
position can have an effect on sound quality. Moving
speakers nearer to walls or corners will increase bass
output, but also may make them sound "boomy." Placing
them farther away from room boundaries tends to
decrease bass output, but can improve stereo imaging.
Room furnishings also play an important role.
furnishings (sofas, carpets, curtains) absorb mid and
high frequencies, which can dull the sound, while hard
surfaces and sparse furnishings tend to brighten it.
These are typically minor variations in sound.
Experimenting with the effects of different placements in
your own listening environment is the key to finding the
sound you like best.
more information,
Here are some tips for maximizing the performance of
your speaker system:
Position the speaker 1.5 times as far away from you
as they are from each other. (Fig. 4)

Left and Right speakers should be equidistant from
the listening position.
Try to keep tweeter height close to ear level when in
the listening position.
Bookshelf speakers should be placed upright.
Try to keep the speakers near the front edge of
shelves or cabinets.
Point them inward slightly toward the listening
position.
