DLS Performance RCS10.D2

The DLS Reference RCS10.D2 is a powerful 25 cm (10-inch) subwoofer that combines impressive bass performance with an exceptionally slim design. As part of the DLS Reference Series, it was developed specifically for music lovers who value a warm, precise, and powerful sound.

With an installation depth of just 97 mm, the RCS10.D2 is ideal for space-saving installations. It delivers exceptional sound quality even in enclosed enclosures with a volume of 10 to 15 liters. The high-quality sandwich composite diaphragm, a robust 63.5 mm voice coil made of four-layer copper wire, and a powerful ferrite magnet ensure controlled bass reproduction.

Thanks to its dual 2-ohm voice coils, the subwoofer can be flexibly configured for 1 or 4 ohms and optimally adapted to different amplifiers. With a 600-watt RMS power handling capacity and a linear cone excursion of ±11 mm, the RCS10.D2 offers an impressive combination of power, sound quality, and compact dimensions.
