SETTING UP YOUR PRIME SPEAKERS ACOUSTICS & ROOM PLACEMENT
5
Toeing-in the loudspeakers 5-10 degrees can often improve imaging, however this
is also a function of the distance from nearby boundaries and the ratio of direct-
to-reflected sound, so experimentation with toe-in is recommended to obtain
optimal results.
The location of the front loudspeakers relative to nearby boundaries will excite
various room modes (a complex pattern of standing waves with associated peaks
and nulls), which will affect the bass response of the loudspeakers. Generally,
placing the loudspeakers closer to room boundaries (particularly corners) will
increase the bass response. Conversely, moving the loudspeakers away from
boundaries and corners will reduce the bass response. Due to the complex
interaction of the loudspeakers with nearby boundaries/corners and your listening
position, significant changes to the bass response can occur with very small
changes in either loudspeaker location or listening position, so experimentation
with both placement and listening position is recommended to obtain optimal
results.
Center Channel Placement
The center channel should be placed directly on-axis, relative to the primary
seating position. As with the main front speakers, placing the tweeter at/near
head level when seated is optimal. But depending on the placement of the video
display or projection screen, this is not always possible.
If the center channel must be located below head level, then an upward tilt of the
speaker is recommended to improve mid/high frequency response and dialogue
intelligibility.
Note:
When purchased as a matching surround package, the versatile Prime
Satellite functions as all channels of the system, including the center channel.
