User manual DLS W612

[. . . ] 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. The size of the enclosure is decided by the speaker data. SEALED ENCLOSURES Sealed enclosures are easy to build. [. . . ] If you have an amplifier without built-in crossover you must use a passive crossover between amplifier and subwoofer like in this example: 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. The sound from the port must come out in the same phase as from the speaker otherwise the result is bad. The size of the vented enclosure is decided by the speaker data just as for the sealed one. The size of the vehicle often decides the practical size of the enclosure. A smaller enclosure has a higher resonant frequency than the larger one. The size of the enclosure should not be so big that the speaker plays below it´s own free air resonance (Fs), then it looses in power handling capacity. The port does not have to be fully inside the enclosure as long as the area and length are correct. Sometimes you need two or more ports in an enclosure. You can convert from one to two or more ports as long as the total port area is the same. All DLS subwoofers works well in vented boxes. + BANDPASS ENCLOSURES C In all bandpass enclosures the speakers are hidden inside the enclosure, all sound is coming out through the ports. There are different types of bandpass enclosures and they have in common that they are a bit more difficult to build. Most DLS subwoofers can be used in bandpass enclosures. Connected with a 12 dB passive low-pass x-over = 10 mH coil in series and a bipolar capacitor of 300 microFarad in parallel. Crossover frequency is 95 Hz. 87654321 87654321 87654321 87654321 L TECHNICAL SPECIFICATIONS FOR DLS REFERENCE SUBWOOFERS W610 Size Impedance Nom. range Sensitivity Voice coil diameter Voice coil height Re Voice coil inductance, 1 kHz BL product X-max Suspension compliance CMS SD- Effective piston area Resonant freq.

[. . . ] It´s important to do some type of bracing inside the enclosure to avoid vibrations. Volume taken up by bracing should be added to the enclosure volumes. ENCLOSURE PLACING IN DIFFERENT TYPES 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. [. . . ]
