Thank you for your support of Kicker products, and especially our subwoofers. The KICKER subwoofer has
always been at the forefront of speaker technology and the latest versions are no different. Our technical
and R&D staffs have designed some extreme enclosures beyond the sealed boxes to give the end user
some choices when it comes to earth shaking bass in their car. After all, that is what we are famous for!
In this manual we explore some applications for KICKER subwoofers complete with box drawings and cut
sheets plus some important information regarding the break-in period for our speakers.
Important Break-In Information:
Due to the complex nature of any speaker, it requires time to break-in. Especially in sealed enclosures,
break-in is a must in order for woofers to produce optimum low bass response. Approximately two weeks
of daily playing will allow the suspension to break-in and reach its optimum equilibrium. The “broken-in“
sub will exhibit stronger bass performance, smoother response, and greater low bass extension.
For those of you with more sophisticated audio equipment, KICKER subwoofers can be broken-in on the
test bench overnight with the following procedure.
Freeair Break-in Procedure
1. Connect the speaker to a power amp of about fifty watts or more. The speaker should not be mounted
in any enclosure - just freeair.
Please make sure it will not walk off the bench while it is playing!
2. Connect an audio generator to the input of the power amp, and adjust the generator to approximately
the frequency in the chart below.
3. Now adjust the gain on the amplifier and generator so that the cone is moving to Xmax. This can be
determined visually by looking at the “blur depth” of the logo on the ISD. A close approximation will do. See
chart below.
Model Set Audio Generator at(Hz) Blur Depth
Comp8 37 3/4”
Comp10 32 3/4”
Comp12 28 7/8”
Comp15 17 1”
Comp8VR 39 3/4”
Comp10VR 31 7/8”
Comp12VR 25 7/8”
Comp15VR 20 1”
Comp18VR 17 1”
S8L5 45 3/4”
S10L5 35 1”
S12L5 30 1”
S15L5 20 1-1/4”
S8L7 45 3/4”
S10L7 35 1”
S12L7 30 1”
S15L7 20 1-1/4”
NOTE: Keep in mind that as the speaker is used under normal conditions the break-in will continue, so if
you don’t have time for the complete break-in period the speaker will still break-in itself under normal
usage.
