4. of the enclosure is decided by the speaker data SEALED ENCLOSURES Sealed enclosures are easy to build The size is not critical but it can t be too small The speaker data such as Fs Qts Vas and X max decides the size of the enclosure Large speakers need larger boxes Two speakers need a box of the double size etc The enclosure must be completely air tight A sealed enclosure should be filled with acoustic wool up to 75 100 A sealed enclosure has a lower efficiency than vented enclosures but they can handle high power and are 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 The Nobelium subwoofers can be used in sealed enclosures 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 Asmaller 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
5. ULTIMATE Nobelium SERIES SUBWOOFERS Nobelium is a radioactive metal with atomic number 102 It is named after the Swedish scientist Alfred Nobel Nobelium 10 Nobelium 12 Nobelium 15 WELCOME Thank you for buying a DLS ULTIMATE Nobelium subwoofer The subwoofer must be installed correctly in order to work well This manual will show you how to install it like a pro 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 In open air installations the power handling capacity is reduced by 30 from the nominal value We dont recommend open air installations for Ultimate Nobelium subwooers CONNECTION OF 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 Two 4 ohm subwoofers are often connected in stereo mode since most amplifiers can t handle bridge mode loads below 4 ohms The Iridium subwoofers have dual four ohm voice coils Each voice coil has an impedance of 4 ohms If they are connected in series the resulting impedance is 8 ohms If they are connected in paral

7. etween trunk and interior of the vehicle In this case a band pass box could be a better choise All volumes are inside measures Volumes occupied by speaker and ports have already been added to the given enclosure volumes Use conical bass ports for best result DLS BP 75 or BP 110 If the ports are too long for the box you can use a bend Either cut the tube and glue it together in angle or use factory made tube bends It s easier to use the factory made ones The total length must be the same as for a straight tube Make the measure in the center of the tube The port opening inside the enclosure must not be closer to an interior wall than 3 75 mm otherwise it will have negative effects on the airflow The enclosure must be very steady and completely air tight Use 22 mm particle board or 19 mm MDF board The particle board has a self resonant frequency of 14 Hz while the MDF has a resonant frequency of approx 400 Hz 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 DAMPING Most enclosures should be damped inside with syntetic acoustic wool or damping mat line Attach the damping ma terial on the wall opposite from the speaker and port A sealed enclosure should be filled up to 70 100 with acoustic wool In a vented enclosure the speaker and port should be on the same side otherwise a fade out
8. lel the resulting impedance is 2 ohms 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 voice coils 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 mm For example DLS SC 2x4 If you have an amplifier without built in crossover you must use a passive crossover between amplifier and subwoofer like in this example one crossover for each voice coil Component values are for 4 ohms L T 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 Active filter Amplifier Connection in mono bridge mode with an active x over Voice coils connected in series If you have a 1 ohm stable amplifier the voice coils should be connected in parallel for best performance for example on a DLS monoblock Valid from 2005 07 04 SUBWOOFER ENCLOSURES GENERAL Build your enclosure in a stable and airtight material The best is MDF board 19 mm or particle board 22 mm 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
