because that is the location of the highest level of bass energy. You can
also consult acoustic software and let it determine where to place them.
This also applies to any absorption and diffusion products.
Equalizers
Equalizers are a kind of sophisticated audio filtering device, used to
compensate for room acoustics, speaker deficiencies, and to achieve a
flat response. The two types of equalizers are graphic and parametric.
Graphic Equalizer
Graphic equalizers typically have multiple adjustable settings that can
range from one full octave to one third of an octave, and are used to
achieve a flatter frequency response from an audio system in a specific
acoustic space. Graphic equalizers use a set of predetermined frequency
bands to adjust the amplitude of the waveform at specific frequencies.
The center frequencies that are used and bandwidth affected by graphic
equalization are predetermined and cannot be altered. This allows only
a change in amplitude within each predetermined frequency range. The
graphic equalizer allows a greater range of control than offered by the
treble and bass controls.
Graphic Equalizer
Parametric Audio Filters
Parametric equalizers permit an adjustment to a signal's frequency
response with complete choice over how to divide up the signal and
adjust it using amplitude, center frequency and bandwidth (octave).
When a signal is parametrically equalized, its amplitude is changed at a
selected center frequency and over a selected range of frequencies on
either side of the center.
