Speaker Placement
We can calculate what the most strongly reinforced frequencies in a room will
be by the formula shown below:
Since the human ear is rather poor at localizing radiation frequencies below 125
Hz, good results may be obtained in a variety of room placements. Careful
adjustment of the convenient panel controls will lead to seamless transition.
Resonant Frequency = (1130 ft/sec) / (ft. between boundaries x 2)
For example, a room with an 8 ft. ceiling height has a strong resonance at:
(1130 ft/sec.) / (8 ft. x 2) = 71 Hz.
Low frequency reinforcement occurs whenever woofers are placed near
room boundaries. The distance from the walls, floor and ceiling correspond to
the wavelengths of the frequencies which will reflect
IN-PHASE
and thus
reinforce bass output. Therefore, the actual dimensions of your listening room
play a definite role in what ultimately arrives at your ear.
