Designed and engineered in the USA, this product combines innovative technology with the finest materials to consistently deliver Absolutely State of the Art™ performance, sound quality, reliability, and value. This PrecisionPowerTM product reflects our commitment to offer you unparalleled performance and quality for years of dependable service and listening enjoyment. Included in this manual are a number of different enclosure suggestions. These are by no means the only enclosures to use, but they provide a starting point. To determine the correct enclosure for your needs many factors must be addressed (amount of power, vehicle, placement, crossovers, etc.) Therefore, as always PrecisionPowerTM recommends that your subwoofer be installed by an authorized PrecisionPowerTM dealer CAUTION Extended use of a high powered audio system may result in hearing loss or damage. While PrecisionPowerTM systems are capable of “Concert Level” volumes with incredible accuracy, they are also designed for you to enjoy at more reasonable levels all of the sonic subtleties created by musicians. Please observe all local sound ordinances. 3 SPECIFICATIONS Directed Part Number Model Number Thiele/Small Parameters Fs (free-air resonance, Hz) Vas (equivalent compliance, cu. ft.)

PrecisionPowerTM woofers are designed for sealed enclosures and vented enclosures. Sealed enclosures are generally considered the most versatile for all music types and are the easiest to build. They will also give high power handling with a wider range of frequencies. The enclosure must be absolutely air tight. Use a high quality wood glue for all seams of the enclosure. The enclosure should also be screwed together. We recommend to use ¾" MDF for the following enclosures. As MDF is a porous material it is best to also seal the inside of the enclosure. 14 PCX 102 and PCX 104 Box Recommendations —External Dimensions— A = 12 in. B = 12 in.
