User manual DLS NORDICA 12

[. . . ] Larger enclosures must have bracing inside to avoid vibrations. The enclosure must be completely airtight. Use sealing compound in all joints, also around the cable terminals. [. . . ] Make sure to connect in ways that don't ruin the amplifier. If you have a DLS Ultimate amplifier it's possible to connect two subwoofers in parallel, these amplifiers are 1 ohm stable. We also recommend the use of a subsonic high pass 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 AWG11 (4 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. Break-in period Allow the speaker to play for at least 15-20 hours. After this time the performance is correct. Enclosure damping Most enclosures should be damped inside with synthetic (acoustic) wool or damping mat (line). Attach the damping material on the wall opposite from the speaker and port. In a sealed box we recommend the use of damping wool. 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.

Nordica 10 & Nordica 12 have a design with "open voice coil" for improved cooling of the voice coil. This construction also give the best sound performance. To prevent dirt from entering the voice coil gap, follow these instructions: - Keep the speaker in the plastic bag until it is time for installing the speaker in the box. [. . . ]
