User manual DLS RW10I

[. . . ] REFERENCE SERIES SUBWOOFERS Welcome Thank you for buying a DLS Reference subwoofer. Install the subwoofer yourself if you feel confident with our instructions and if you have the proper tools. However if you feel unsure, turn over the installation job to someone better suited to it. [. . . ] Most amplifiers today have built-in lowpass crossover and possibilities to connect your subwoofer in bridge mode. Please note that the RW10i and RW12i subwoofers have a 2 ohm impedance, if connected in bridge mode to your amplifier the resulting impedance is 1 ohm. If you have a DLS Ultimate amplifier it´s possible to connect the two subwoofers in parallel, these ampliers are 1 ohm stable. For example DLS SC 2x4. Important! Think of the speaker weight when you do your install. Use heavy bolts when fastening the sub to the enclosure baffle. Enclosure placing in different type of vehicles In small vehicles like VW Golf, Peugeot 306 and similar the bass box should be installed with both speaker and port directed backwards. This way of mounting is valid for all types of vehicles where the trunk is incorporated with the inner compartment. In sedan vehicles with the passenger compartment separated from the trunk, the enclosure should be installed with booth speaker and port directed towards the rear seat. Some cars have an opening in the middle of the rear seat for loading skis etc. You can install the enclosure behind this opening and direct speaker or port through this opening. There must be some free space in front of the port, (between the rear seat and the port opening). In large vehicles like station wagons the best sound is achieved with the enclosure installed behind the rear seat with booth speaker and port directed backwards. Alternatively you can install the enclosure on one side of the luggage compartment. Running-in period Allow the speaker to play for at least 15-20 hours. After this time the performance is correct. Warranty service This speaker is covered by warranty, depending on the conditions in the country where it is sold. If the speaker is returned for service, please include the original dated receipt with the product. About the recommended enclosures The performance of these recommended enclosures varies from vehicle to vehicle. [. . . ] This is a drawing for the 20 litre box and the separate boards needed to build a suitable enclosure. Technical drawing for a 30 litre enclosure. The RW12i works well in a 30 litre sealed enclosure. This is a drawing for the 30 litre box and the separate boards needed to build a suitable enclosure. Calculate your own enclosure Box volumes: When calculating the inner volume of an enclosure you just multiply the width (W) x height (H) x depth (D). A trapezoid box is calulated as this: W UD H LD Be sure to measure the inside dimensions. Vol=width (W) x height (H) x upper depth (UD) + lower depth (LD) 2 [. . . ]
