CompVR Woofer Technical Manual Kicker Comp Subwoofers Recommended Applications / Version 2.
Features ! Hemispherical Polymineral Cone with Inverted Structural Dome (ISD) Means high rigidity under pressure for accurate linear control, low enclosure pressure loss to reduce "pump-down", high internal dampening, and excellent sunlight, pollution and moisture resistance ! WARG (Wrap ARound Gasket) Instead of using cork gaskets, which can separate, the Comp VRs have a one piece gasket that wraps around the front and back of the mounting flange. It is more durable and ergonomically pleasing to the eye.
Features cont. ! High-Temp Kaptonfi Voice Coil Former Heat is the primary enemy to the life of a speaker, which is one of the reasons we use Kapton® voice coil formers. Kapton® is a man-made product that is light, durable and heatresistant. The Kapton® former acts as an insulator to keep the heat of the voice coil from breaking down the adhesive that connects the voice coil to the cone. During high excursion and prolonged exposure to heat, the Kapton® former holds it’s shape and does not expand or contract.

Thank you for your support of KICKER products. Once you have had a chance to see and experience the capabilities of the new KICKER CompVR subwoofers, we believe that you will be as excited as we are about these speakers! The CompVRs truly set a new standard for bass performance. This latest revision of our KICKER CompVR Subwoofers Recommended Applications/Enclosures Technical Update brings together all of our Kicker CompVR woofers into one manual.
Sealed Enclosure Applications The KICKER CompVR woofers are real performers in sealed enclosures, producing the tight, defined, and accurate bass response you would expect from a KICKER. They will operate in larger sealed enclosures for ultra sound quality (SQ) applications without significantly sacrificing their power handling. This extra bass extension and smoothness can be obtained by simply using a larger sealed enclosure.
Characteristics of Sealed Enclosures The most basic and simple of all speaker enclosures is the sealed box or acoustic suspension design. The acoustic suspension design has several advantages; it is easy to build, easy to tune and offers high power handling, tight response and extended low end output. Acoustic suspension enclosures produce lower bass because they roll off at 12 dB per/octave. Cone motion is better controlled at all frequencies because of the constant pressure on the back side of the cone.

Ported/Vented Enclosure Applications Ported CompVR drivers incorporate massive slot loaded ports with ultra low air velocity for ground pounding street bass that will make your hair stand on end (if you have any left)! These are the enclosures of choice for outrageous street bass and SPL contests. The following chart shows three recommended ported enclosures for each CompVR driver. Compact has increased bass efficiency over a sealed enclosure, yet can still fit in tighter applications.
Characteristics of Vented Enclosures A vented enclosure is not much more complex than a sealed box. It consists, basically, of a box with a hole in it. However, despite its simple design, vented boxes are considerably harder to get good performance from than sealed boxes - although many times the extra effort can be worth it. The vent in the enclosure interacts with the volume of air in the cabinet and with the driver to help increase output and reduce cone excursion at and around the tuning frequency.

Box Building & Mounting Hints All the cubic feet numbers given in the supplied charts include the displacement of the woofer. For the ported boxes the displacement of the port must be added to the final design. It will be impractical to use round ports for these designs. The rectangular port information given will yield the best results. Always use 3/4” or thicker MDF and make sure all the joints are secure and well sealed. The peak pressure in a ported box can exceed that of a sealed enclosure.
Box Building & Mounting Hints If you would like to use a vented enclosure, but the box designs we provide you with (in this manual) do not fit because of width or depth the designs can be modified. The shape of the enclosure is not vital, but The Volume Is. The volume, of the design you choose, must stay the same. The following diagrams provide you with some help to insure your enclosure is built correctly.
Box Building & Mounting Hints Here are a couple more examples of the different shape enclosures you can build. The woofer can be mounted on the same side as the port or the back side of the enclosure can be slanted to fit up against your back seat.. On the cut sheets we provide, change the dimensions to accommodate the woofer and the vent on the same side.
Wiring Options The following diagrams are the most popular wiring configurations when using Dual Voice Coil woofers. They show a typical single channel wiring scheme. Check the amplifier’s owners manual for minimum impedance the amplifier will handle before hooking up the speakers. Remember: 4 Ohm mono is equivalent to 2 Ohm stereo.
