Effects of the Contouring Switches
for most rooms. However, if you feel that the bass in your
system is too strong relative to the mid-range and high
frequencies, simply select the -3 dB

-3 dB position. This switch
position will attenuate the woofer response by 3 decibels
below 200Hz. With the Flat
Flat Flat Flat Flat position selected, the Bass
Contour circuit is removed from the audio signal path,
thereby eliminating any possibility of signal degradation
caused by added circuitry.

switch that allows you to tailor the mid-range response
(presence) of the Quest. The Flat

Flat position is considered the
normal setting for most rooms. However, if you would like
more presence, select the +2dB

setting will cause a 2 decibel rise centered around 2.5kHz.
With the Flat

Please refer to the graphs in
Figure 5 showing how these
switch settings effect the response of the Quest.
Some experimentation with these two switches will allow
you to find the optimal tonal balance to meet your specific
tastes, room environment and audio equipment.
The passive crossover elements in the Quest are very
complex electrical devices with unique voicing and equal-
ization. They cannot be replaced with a standard electronic
crossover. If, at some time, a properly designed electronic
crossover for the Quest becomes available from Martin-
Logan, the owner of warranty will be sent notification.

Because of the wide variety of room environments, record-
ing techniques and customer preferences that we feel are
important issues for today's premier loudspeaker designers
to address, we have provided the Quest with two switches
that will give you more flexibility and control over the final
sound.
