If you are using 0.625 in (16 mm) thick material, subtract 0.25 in (6.5 mm) from each dimension. Do not use any material with a thickness of less than 0.625 in (16 mm) as this may compromise the rigidity of the enclosure.\u003cbr\u003e* All enclosure volumes listed above are net internal volumes! Driver displacement, port displacement and brace displacement must be added to obtain the final gross internal volume. All enclosure dimensions above have already taken this into account.\u003cbr\u003e* When using multiple subwoofers in a common enclosure you will need to recalculate the enclosure and port dimensions. For assistance please contact your authorized JL Audio dealer or JL Audio Technical Support.\u003cbr\u003e* We recommend the use of this speaker in a bi-amplified system using high-quality satellite speakers and a high-quality amplifier. We do not recommend the use of this subwoofer with a passive crossover (coil), as this type of device will adversely affect performance.\u003cbr\u003e* All specifications are subject to change without notice.\u003cbr\u003eSafety Notice\u003cbr\u003eProlonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss. This high-performance speaker can exceed this level. Please exercise restraint in its operation in order to preserve your ability to enjoy its fidelity.\u003cbr\u003eWhen installing a subwoofer in your vehicle, it is extremely important to secure the enclosure firmly. We recommend bolting the enclosure through the metal of the floorpan or the frame of the vehicle with large diameter washers for reinforcement. If an enclosure is not firmly attached, it can become a projectile in a collision. This is particularly important in a hatchback, station wagon, sports utility vehicle, or van.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003ePorted Enclosure Specifications\u003c\/h2\u003e\n\u003cp\u003e\u003cimg alt=\"Table_Image\" src=\"http:\/\/mediacdn.jlaudio.com\/media\/mfg\/9013\/media_image\/live_1\/Round_Ported_ENC_Dimensions.png?1302929193\"\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWall Thickness 0.75 in \/ 19 mm\u003c\/li\u003e\n\u003cli\u003eFront Baffle Thickness 0.75 in \/ 19 mm\u003c\/li\u003e\n\u003cli\u003eVolume (net int.) 0.50 cu ft \/ 14.2 L\u003c\/li\u003e\n\u003cli\u003eExternal Width (W) 13.0 in \/ 330 mm\u003c\/li\u003e\n\u003cli\u003eExternal Height (H) 10 in \/ 254 mm\u003c\/li\u003e\n\u003cli\u003eExternal Depth (D) 11.125 in \/ 283 mm\u003c\/li\u003e\n\u003cli\u003eInternal Port Diameter (ID) 2 in \/ 51 mm\u003c\/li\u003e\n\u003cli\u003ePort Length (L) 10 in \/ 254 mm\u003c\/li\u003e\n\u003cli\u003eTune to 38 Hz\u003c\/li\u003e\n\u003cli\u003eF3 39.10 Hz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNote: Preliminary Ported Enclosure Specs\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eSafety Notice\u003cbr\u003eProlonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss.
