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 midbass due to the fact that speakers mounted in the doors 
or kick panels cause resonance’s or peaks in the response curve. These 
peaks in the midbass can actually mask or block sounds in the all-impor-
tant midrange area causing your system to sound dull or lifeless.
Midrange: 300Hz to 3Khz – Musical instruments, vocals, mid-range 
percussion and many things we associate with imaging and staging hap-

enough energy the midrange sounds empty and dry.
Treble: 3KHz and Up – If midrange is the cake, then these high or 
upper frequencies are considered the frosting. Many autosound systems 
start a gradual decline in this area which is why speaker placement is 
very important. The DQDX only gives you a few controls in this area 
because too much boosting can really make a speaker sound un-natural.
