you to select the type of low frequency

The

0 dB position is considered the normal
setting for most rooms. However, if you feel
that the bass in your system is too light
relative to the mid and high frequencies,
simply select the

+2dB position. This switch
position will increase the output of the woofer
by 2dB.
Some experimentation with these two switch
settings will allow you to find the optimal
tonal balance for your specific taste, room
and equipment. Below is a graph showing
how the +2dB switch setting affects the
frequency response of the Sequel II.

Vertical Bi-amping, each of
the stereo amplifiers is dedicated to one speaker. For
instance, the left channel of each amplifier drives the low
pass section while the right channel drives the high pass
section. To
