User manual KICKER CVR18

[. . . ] Perimeter Venting for measurably lower operating temperature and freer cone motion. Hi-Temp Kaptonfi Voice Coil Former protects against warped, rubbing voice coils. Dual Long-Throw Voice Coils A speaker can obtain extreme Xmax only when the voice coil is long enough and can sustain the stress. Spring-Loaded Nickel Plated Terminals for solid connections with large gauge speaker wire. [. . . ] Again, this will severely affect the power handling capability of the woofers that are still working. Another benefit of a divided enclosure is that the divider helps strengthen the enclosure. A large common enclosure will have much bigger panels than one that is divided. Large panels tend to flex more and can cancel some of the woofer's output. 3 Sealed box mounting 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 following information will give you examples of compact sealed enclosures for the Kicker Comp woofers. They have very high power handling and massive amounts of high impact bass. The given volumes are the minimum recommended and include driver displacement. Maximum volumes for KICKER CompVRs are CVR8-1. 8cf, CVR10-3. 0 cf. , CVR12-4. 6 cf. , CVR15-5. 2 cf. As the sealed enclosure volumes increase, the response will shift from high impact bass to a smoother and more extended low end.

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.
