one of the most difficult to properly reproduce.
Most people prefer their bass frequencies to be
6 to 9 dB louder than the rest of their system,
although there are some crazy folks that prefer
their bass substantially louder. The key in this
area is to have enough speakers and power to
produce the amount of bass you desire. But don’t
use the controls on the DQL-8 to try and force
your speakers to produce sounds they can’t.
Too much bass boost creates a condition called
“speakerus explodus”, which is not pretty to hear
or watch.
Midbass: 100 Hz to 300Hz: - The phrase,
“too much of a good thing”, can certainly apply
to the midbass frequencies. This is the transi-
tion area of the audio spectrum that is an octave
above your sub-bass frequencies and several
octaves below your midrange. Most autosound
systems have too much mid-bass due to the
fact that speakers mounted in the doors or kick
panels cause resonances or peaks in the response
curve. These peaks in the mid-bass can actu-
ally mask or block sounds in the all-important
midrange area causing your system to sound dull
and lifeless.

Midrange: 300Hz to 3kHz - Musical
instruments, vocals, mid-range percussion and
many things we associate with imaging and
staging happen in this area of the bandwidth.
For that reason you will want to keep this area
as smooth and balanced as possible. Too much
boosting can make you feel like you are listening
to your system in a tile bathroom. Not enough
energy in the midrange sounds empty and dry.
Treble: 3KHz and Up - If midrange is the cake,
then these high or upper frequencies are the
frosting. Many autosound systems start a grad-
ual decline in this area which is why speaker
placement is very important. The DQL-8 only
gives you a few controls in this area because too
much boosting can really make a speaker sound
unnatural.
