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 front panel controls will
lead to seamless transition.

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. In fact, rooms tend to have their own set of favored frequencies.

We can calculate what the most strongly reinforced frequencies in a room
will be by the formula shown below:

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.
