A Low pass lter will allow only
the bass frequencies to reach the
woofer making for a more natural
transition to the higher frequency
drivers. Check your ampli er’s
manual for details.
We recommend using an
electronic subsonic lter. This will
help to protect the woofer from
extreme low frequency distortion.
Many ampli ers are equipped
with this type lter. Check your
ampli er’s manual for details.
This subwoofer is equipped with
quick disconnect type terminals.
Use crimp type terminals or solder
the wire directly to the terminals.
Depending on the number of woofers you intend to use,
you can con gure the wiring to provide the best impedance
load for your system. Below are some examples. Consult
your ampli er’s manual for recommendations.
