Music Placement
If you wish to seriously listen to music, these general placement guidelines should help:
● The distance between your front LR speakers should be approximately one-half their distance
from your favorite listening position.
● If you point the front of the speakers directly towards the prime listening position, you will
achieve the most precise imaging. You will also receive the maximum amount of direct radiated
high frequency energy. If you have a “bright” or “hard” sounding room environment, aiming the
speakers straight out into the room (or just aiming them partially towards you) may make for a
more natural and pleasing sonic balance.
● The distance from each speaker to the three closest room surfaces should be different.
● In most rooms, you shouldn’t place your speakers in the corners.
The goal is to reproduce accurate musical timbre and natural sound. Additionally, a well set-up stereo
pair of speakers will create excellent imaging and a cohesive representation of the soundstage.
Placement in the room and your listening position have an enormous impact on the ultimate sound
you will achieve from your system. The most important thing is to be creative! Try placing your
speakers along the long wall instead of the short one. Toe the speakers in or point them straight ahead.
Pull them away from the wall or push them close. Don’t be timid. You’ll find that moving your
speakers, even a few inches, can dramatically change and possibly improve their sound.
Setting Speaker Volume Levels.
You should set all the speakers in the surround sound system to the same volume level, hopefully
using an SPL (Sound Pressure Level) meter. As of this writing you can buy a fairly inexpensive one at
Radio Shack
®
stores that will help you properly set up your system. Set the meter to C weighting, Slow
response and hold it with the microphone pointed up, while you are seated in the prime listening
position. Please try to avoid the temptation of setting the surrounds and subwoofer levels too high.
Remember, in a really good movie theater you aren’t aware the surrounds are even there, the vast
majority of the time. Too much surround level and you will constantly be distracted from the action
up on the screen.
Mounting
The T90 LR and SR speakers can be mounted in a variety of ways:
On a bookshelf Self-adhesive rubber feet to protect the speaker and the shelf are included.
On speaker stands Atlantic Technology’s optional ST 176 speaker stands provide a good height (29"
above the floor) for most rooms. There are 1/4" x 20 bolts included in the stand hardware package that
screw into the matching inserts in the back of the speakers. This makes for an exceptionally secure and
solid stand mounting system.
On the wall To mount your speakers on a wall, we have supplied metal keyhole brackets that attach
to the back of the speakers. You’ll need to attach the keyhole bracket to the appropriate 1/4" x 20
threaded insert on the back of the enclosure, using the supplied, 1/4" x 20 bolt.
