User manual DLS RMW10

[. . . ] In "open air" installations the power handling capacity is reduced by 30% from the nominal value. We don't recommend "open air" installations for Reference subwooers. Subwoofer enclosures, general Build your enclosure in a stable and airtight material. The size of the enclosure is decided by the speaker data. Vented enclosures A speaker in a vented enclosure has a higher efficiency (+3 dB) and higher power handling capacity than in a sealed enclosure. In a vented enclosure the sound from the speaker and the port work together creating a higher sound level. [. . . ] 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 vented enclosure the speaker and port should be on the same side, otherwise a fade-out of some frequencies can occur. In most vehicles, except for SEDAN cars, the speaker and port should be directed backwards for best result.

It is more difficult to get a tight and well defined bass in a SEDAN vehicle because of the tightness between trunk and interior. In most cases the recommended enclusures on next page is the best choice. - Volumes occupied by speaker and ports have already been added to the given enclosure volumes so don't add any more volume. The larger one is for the outside, and the smaller one should be attached to the tube inside the enclosure. [. . . ] As an alternative the port can also be mounted on the side of the enclosure. 155 Technical drawing for a 26 litre enclosure. The RMW10 works well in a 26 litre vented enclosure.
