Powerful Dual Voice Coil Car Subwoofers

Package Includes: (2) Power Acoustik CBW-124 12 1500 Watt Car Audio Subwoofer DVC 4-Ohm Sub Description: Power Acoustik Caliber subwoofer combines innovative technology with the finest materials to consistently deliver absolutely state of the art performance, sound quality, reliability, and value. The Caliber subwoofer reflects our commitment to offering you unparalleled performance and quality for years of dependable service and listening enjoyment. Subwoofers do not need to have monster magnets to work properly. These all-new drivers are great for the modest powered system and yield great sound quality and much lower bass than the previous models. Each model features a molded Polypropylene cone and Butyl Rubber surround for great performance and durability. Dual 4-ohm voice coils are wound on Kapton formers for versatility and better heat dissipation. Check out the new entry-level drivers and see for yourself that low-cost subs do not have to sacrifice performance! All enclosures should be made of .75” (3/4”) material only. When possible, make the baffle 1.5” (1 1/2) thick and add .75” (3/4”) to the depth of the enclosure to compensate. All volumes INCLUDE vent/port and subwoofer displacements. DO NOT change the volume unless you plan on adding a substantial amount of bracing. For added performance, applying a coat of fiberglass resin to the interior walls will greatly improve sealing the enclosure. Adding a thin layer of poly-fill will improve response by smoothing out reflections within the enclosure.
