KSD C55 Reference Stereo Pair
The KSD C55-Reference features a dedicated 5.5‘ coaxial-driver and a dedicated 5.5‘ woofer, which delivers exceptional sound performance. With maximum neutrality and minimm distortion, every sound and every impulse is reproduced precisely and musically.
It is available in black, white and cherry.




Thanks to phase-linear dispersion using FIRTEC filters and a coaxial design, the C55-Reference is extremely lively and impulse-true with an accurate representation of panorama width and stage depth. Two bass drivers double the cone surface area and, with their two powerful drives, ensure a clean, “boom-free” bass reproduction. The C55-Reference is therefore an ideal monitoring tool for music production, from tracking and mixing to mastering.
And of course it’s also particularly nice to simply enjoy music with the C55 Reference.
