User manual DLS RW12I

[. . . ] Please read the entire manual before beginning the installation. 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. The speakers are designed for enclosure mounting. [. . . ] A sealed enclosure has a lower efficiency than vented enclosures but they can handle high power and is easy to build. A subwoofer in a sealed enclosure creates a tight bass suitable for the audiophiles listening to classical music, jazz and soft rock. RW10i and RW12i are designed for use in sealed enclosures. Connection of the subwoofer How to connect depends on what type of amplifier you use. The best is to follow the instructions given in the manual for the amplifier. 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. This means that your amplifier must be 1 ohm stable. Make sure to connect in a way that don´t ruin the amplifier. If you have a DLS Ultimate amplifier it´s possible to connect the two subwoofers in parallel, these ampliers are 1 ohm stable. We also recommend the use of a subsonic highpass filter. This gives a better bass reproduction with less "rumble". In most DLS amplifiers this feature is already built-in. For wiring use high class speaker wires, min AWG13 (2. 5 mm2). 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. Alternatively booth speaker and port can be directed upwards. 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.

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). [. . . ]
