Because there are no universally accepted methods for loudspeaker
measurement, frequency response specifications may be stated by most
manufacturers without reference to measurement techniques and/or specific
locations in rooms. Magneplanar loudspeaker frequency response curves are
minimum average performance levels that may reasonably be expected in
normal installations.
**
New Magneplanar MG20.1 speakers will not display their full bass potential.
After a month or two of use the bass response will lower 5Hz or more. At this
point the response will be realized. While this 5Hz or more of lower bass
response is important, the most important factors in obtaining good bass
response from the MG20.1 speakers are room size and geometry, wall material,
and speaker placement.
