Use our wiring assistant for easy speaker and subwoofer connections! The correct connection is important for your amplifier! Low-impedance operation can damage the amplifier! The datasheet shows you which connection each amplifier is designed for!
Our port calculator shows you the tuning characteristics of your enclosure! The net volume is always particularly important here; calculate the subwoofer’s actual resonant chamber volume beforehand to get the correct result. The net volume is calculated by subtracting all dead spaces and is crucial for enclosure design.
The DLS Reference RCS12.D2 is a high-quality 30 cm (12-inch) slim subwoofer that combines powerful bass reproduction with an exceptionally slim design. As part of the DLS Reference series, it was developed for discerning music lovers who value precise, dynamic, and natural low-frequency response.
With a power handling capacity of 600 watts RMS and an installation depth of just 107 mm, the RCS12.D2 delivers impressive bass performance while taking up minimal space. The high-quality sandwich composite cone, combined with the sturdy die-cast aluminum basket, ensures controlled, detailed sound reproduction and high mechanical stability.
The 63.5 mm, four-layer copper voice coil mounted on a TIL voice coil carrier ensures reliable power transmission. Thanks to the dual 2-ohm voice coils, the subwoofer can be flexibly configured for 1 ohm or 4 ohms and adapted to different amplifiers.
Thanks to its design, the DLS Reference RCS12.D2 is particularly well-suited for compact, sealed subwoofer enclosures, but can also be used in tuned bass-reflex enclosures.
