How to Place Your Speakers
The VR-M80 and VR-M90 were designed to deliver exceptional bass extension and tonal balance, regardless of
where they are placed. However, for optimal results, it is advisable to position the rear of the speaker to be at least
3 inches (76cm) or more away from the wall or curtains that are behind it. The speakers should also be at least 2 feet
(0.6m) from the corners of the room. Putting the speakers too close to a corner can produce an unnatural bass
reinforcement that detracts from their balanced, uncolored sound. For optimal bass performance when a speaker
must be placed in or near a corner, position it so that the distance to the side wall is different than the distance to
the rear wall.
Most people like to hear a realistic soundstage, as they would from a good seat in a concert hall. To achieve this
effect, place the speakers 6 to 12 feet (2-4m) apart, so they form a triangle with your favorite listening position.
If your listening position happens to be less than the distance that the speakers are apart, then you may prefer to
"toe-in" the speakers slightly.
Listening Room Considerations
The listening room's dimensions, furnishings and wall types will all contribute to the way any loudpeaker will
respond. If your room is square (same length and width), you may experience low frequency standing waves that
can reduce overall clarity. Experiment with different placements and toe-ins to avoid this. Also, the more fabric
material there is in a room (curtains, sofas carpets, etc), the more that high and mid-range frequencies will be
dampened. Conversely, the more exposed bare walls that there are in the room, the brighter the speakers will
sound. Thus, you may also want to experiment with speaker placements with these considerations in mind.
