The EQL comes with an 18 dB per octave

Programmable Frequency Match low-cut filter

module already set to 33 Hz. This will act as a

woofers (i.e., 6" or 8"), use a higher frequency

Programmable Frequency Match module.

Additional modules with pre-set frequencies

are available from an authorized AudioControl

dealer, or you can create a custom low cut filter

module by using the following formula
