User manual DUAL DS12

[. . . ] Be careful not to cut or drill into gas tanks, fuel lines, brake or hydraulic lines, vacuum lines or electrical wiring when working on any vehicle. Never run speaker wires underneath your vehicle. Running speaker wires inside the vehicle provides the best protection from exhaust heat and environmental elements. Avoid running wires over, near, or through sharp edged surfaces. [. . . ] · Remember to listen responsibly and respect your ears. Being exposed to sounds over 125dB for even short periods of time can create permanent hearing loss! 6 DS - XS SERIES CALCULATIONS Enclosure Guidelines To work properly, the walls of your enclosure must be free from flexing during high sound pressure generated by your subwoofer(s). For best performance, always use MDF (Medium Density Fiberboard) or Baltic Birch Plywood to build your enclosure. We highly recommend that your wood be at least 3/4" in thickness. The enclosure should be sealed internally with silicon or glue and secured with screws every 4". Assemble the box before cutting the subwoofer hole(s). If the box will be mounted in a vehicle, it should be fastened securely using metal "L" shaped brackets. To build an enclosure, calculations will need to be made using the information found on the following 3 pages. Remember: · Use 3/4" MDF or Baltic Birch Plywood · Use silicon or glue in joints · Use screws every 4 inches We at Dual are diligent in checking the dimensions provided. The engineers, staff and installers provide this information to make your installation go as smoothly as possible. We highly recommend that you personally measure your subwoofer prior to installation to avoid any damage. Please follow the rule "Measure twice, cut once". 7 DS - XS SERIES ENCLOSURE DIMENSIONS Sealed Enclosure 10" Subwoofer Enclosures Good Bass Performance Mini-Enclosure (Vb) Box Volume=. 35 Cu.
