To optimize the subwoofer’s performance you will need some basic
measurement equipment and software. listed below are relatively
easy and inexpensive options:
!
Software:
REW -

- Free
or
Omni Mic -

measurement-system.html
Includes Microphone and uses CD as signal source, minimal physical
connection required.

Measurement Microphone:
UMIK-1 -

or
UMM-6 -

for this guide we will use REW measurement software, but any modern
software should work fine. Since we are measuring bass frequencies
there is no need for high end microphones or hardware to enable the
measurement of high frequencies or distortion.
!
General information
The Magico QSub is designed to add Ultra low frequencies and
improve overall bass behavior in a high end stereo system. The
common cutoff frequency will be 50 Hz and optimal integration will
be achieved when used with Magico S or Q Series loudspeakers, which
employ a sealed box design.
!
We will rely solely on measurements of the bass frequency response.
(Our ears are not sensitive enough to determine the source or the
magnitude of problems in the bass region, yet they easily notice if
there are problems in that region). place the measurement microphone
in the listening position. (for a wider listening area one must take
multiple measurements from a variety of locations and average the
response, this is beyond the scope of this guide)
