KICKER CompVR Sealed Enclosure Applications

A very smooth bass response with good low bass extension is achieved when the Kicker CompVR woofers are mounted in a

correctly built sealed box with the correct airspace. Sealed (acoustic suspension) designs have been a favorite here at Kicker
since the original Competition Series was introduced. We build just about all of our show vehicles with sealed boxes for the
smooth response, good power handling and great sound quality they offer.

Of all the enclosures possible the sealed box is the easiest to build. The two most important

rules are to make it very solid and to seal all the joints perfectly. If the panels of an enclosure
can flex or vibrate you will experience a loss of bass output. You don't want to throw away any
of the output capability of your Kicker CompVR woofers. Sealing all the joints in the enclosure
is necessary to avoid loss of output and driver failure.

The Kicker CompVR woofers will work in a wide range of sealed boxes. The examples below

are given for good all-around 

Street Bass

boxes that will work well for most types of music

without taking up a lot of space. The given volumes include driver displacement. Other shapes
can be used as long as the proper airspace is maintained.

For a more 

Compact

enclosure you can go down to -20% of these examples. The flattest response is achieved by putting

your CompVR in a much larger 

SPL/Deep Bass

enclosure. If your goal is the flattest, most accurate bass, then these are for

you. This is not the best design for most people, however, as power handling is reduced. If you want lots of ground pounding
street bass, stay with the recommended all- around

or Compact enclosures or try one of the vented designs cov-

ered later in this manual. The airspace for the Compact and SQ boxes is as follows:

KICKER CompVR Ported/Vented Enclosure Applications

Almost as easy to build as the sealed box, the vented or ported enclosure can give you more output at certain bass frequen-

cies. Although this design has an output advantage at some frequencies it also has a sharper rolloff characteristic which will
only affect the lowest of bass frequencies. Overall a correctly designed vented enclosure will have some "free" output provided
by the port itself.

One major disadvantage to the vented design is the "unloading" of the woofer at very low frequencies. At a frequency 1/2

octave below the tuning frequency of the enclosure the woofer acts like it has no box to work in and can go to full excursion.
This will be harmful to the woofer's mechanical integrity. It is therefore very important to stay with the recommended designs.
NOTE: The use of a subsonic filter (such as a Kicker SWX - without chips & set to highpass) will significantly increase the power
handling.

The vented box examples detailed in the following drawings are good all-around 

Street Bass

boxes that will work well for

most types of music and deliver considerably more output compared to the sealed boxes.
