Models 4.5 LR, 4.5 C, and 4.5 SR
Note:
Some surround sound decoders and receivers offer a choice of “normal” or “wide-band” modes for the
center channel. The Model 4.5 C was designed to be used in the “normal” mode. Additionally, some discrete
digital Home Theater systems allow you to select between “Small” and “Large” speakers throughout the
system. Since System 4.5 has been designed only to work with an active subwoofer, you should usually set all
the speaker positions to “Small.” However, if you are using the 4.5 PBM subwoofer, please follow the
connection instructions contained in the subwoofer manual.
Surround Effects
The 4.5 SR’s size and shape allows greater flexibility in placement than most conventional surround
loudspeakers. Due to their dipole design’s spatial characteristics, it is possible to place the speakers
virtually anywhere, but usually the best location is straight out to the sides of, or slightly behind the
primary listening area, approximately 1-2 feet above ear level.
Note:
The surround speakers are intended to re-create the ambient sounds taking place in the movie scene.
Throughout most of a movie or TV program you may not be directly aware of the surround speakers presence.
The signals they receive are mostly subtle sounds that should make you believe you’re in the movie.
The orientation of the 4.5 SR’s is important to the proper generation of the involving and diffuse
surround effect. Mount each speaker on the wall or shelf so that the “direct” soundfield is aimed
toward the front of the room, and the “ambient” soundfield is directed toward the rear. To insure this
orientation, make sure that the RIGHT speaker is on the right side wall of the room, and the LEFT
speaker is on the left side wall of the room. They are marked RIGHT and LEFT on the back.
Music Only System (Model 4.5 LR with subwoofer only)
If you are setting up a music only system, begin with these general guidelines:
●
The distance between your speakers should be approximately one-half their distance from your
favorite listening position.
●
Point the front of the speakers straight at you to 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 its three closest room surfaces should be different.
●
In most rooms, you should not 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.
