OTHER ACOUSTIC CONSIDERATIONS

For best fidelity, there are several other factors to keep in mind before you start actual installation.

Concerns and reflections:

When a ceiling speaker is placed close to the comer of a room, bass fre- quencies are emphasized. This can be okay if both speakers are mount- ed near corner (while maintaining stereo imaging), but try to avoid plac- ing just one speaker in a corner and another on a long flat surface.

In general, the best acoustic performance will result if both speakers face a similar type of surface and are placed in similar positions on the same type of wall or ceiling.

Installation Depth:

Russound Ceiling speaker models SP503.1, SP522.1 and SP523.1 require at least 3” of wall depth (measured from the outside surface of the wall). This means that they can be installed in any wallboard between ceiling joists or a 2x4 stud wall. In fact, the dense, rigid nature of plas- terboard or (lath and plaster in older homes) acts as a superb speaker baffle.

When installing the speakers, avoid:

T-bar “drop ceilings” with very thin fiberboard panels which can buzz and vibrate. If you suspect this will happen, reinforce the drop-in panel with wood or particle board.

Any wall which can’t provide proper depth (clearance) for the back of the Russound speaker. This includes brick or concrete walls where the wallboard or paneling is attached to thin furring strips.

Inside wall space less than 10” wide and 24” in height

Ceilings and walls where you know that there are pipes, heating ducts and ESPECIALLY AC wiring in the general vicinity. For example, if there is an outlet along the baseboard, there is often a live wire running partly up the wall at that point. The same applies for ceiling fans, overhead lighting, etc.

DUAL VOICE COIL

Dual voice coil speakers are used to create a stereo sound from one speaker. The left and right inputs are both connected to the two differ- ent inputs at the speaker. The action of two voice coils on one cone simulates a full range mono signal.

Speaker Placement

Figure1 Russound ceiling mount speakers may be used for rear surround sound channels by placing them (1) behind, (2) on each side of the viewing position or (3) in the ceiling just behind the viewers. The available SP550.2 & SP650.1 speakers also make excellent, unobtrusive front channel home theater speakers for 5 channel listening.
