ULTIMATE Iridium SERIES SUBWOOFERS Iridium 10i Iridium 12i iridium 15 WELCOME Thank you for buying a DLS ULTIMATE Iridium 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 Iridium 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 parallel 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 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 RUNNING IN PERIOD Allow the speaker to play for at least 15 20 hours After this time the performance is correct ry Technical Assistance For technical assistance ask the shop where the product was sold or the distributor in your very country You can always phone the DLS Helpdesk in Sweden 46 31 840060 or send an e mail to info dls e Information can also be found on our WEB site www dls se We follow a policy of continuous advancement in development For this reason all or part of specifications amp designs may be changed without prior notice 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
