KSD has been developing and producing studio monitors and mastering speakers for 25 years.
Product design, concept, development in house – handmade and manufactured in Saarbrücken, Germany.
The KSD C55 Reference features a dedicated 5.5′ coaxial-driver and a dedicated 5.5′ woofer, delivering exceptional sound performance. With maximum neutrality and minimum distortion, every sound and every impulse is reproduced precisely and musically. The featured drivers are custom made to KSD spec and proprietary to KSD. The C55 Reference radiates as a true points source and the coaxial design allows the greatest freedom in listening distance and placement, supporting both vertical and horizontal orientations. Six parametric user EQs in the FIRTECTM processor allow perfect adaptation to the listening room and distance.

The KSD B500 Subextension is the ideal partner for expanding the performance of KSD main monitors such as the KSD A500, KSD A200mk2 or the KSD C100 Reference.
In combination with the KSD B500, the main monitors experience extreme relief when it comes to reproducing the lower octave. The double ten-inch drives with 1000W amplifier power per pair not only increase the maximum sound power, but also give the entire system a different level of performance. In interaction with the bass chassis of the top parts, the common membrane area multiplies, resulting in an almost planar wave front in the bass. This significantly improves the room illumination in the bass with fewer mode-related room problems.
To ensure a controlled and powerful reproduction of deep bass frequencies, the B500 Subextension is controlled via the XLR sub-output of the main monitor with time-correct sound conversion using the patented FIRTECTM technology. The digital signal processor linearizes the frequency response, while internal filters allow for precise tuning to the room and application. Additionally, the adjustable delay compensates for any spatial offset between the B500 and the satellites.
Available with either Natural Cherry and Black front panels.

The KSD Linemaster sets a new benchmarks in loudspeaker construction and a new standard for recording and mastering performance. Operating with the highest degree of sonic neutrality, the KSD Linemaster delivers a perfect holographic stage with maximum impulse control at even the highest monitoring levels.
Technically realized by our phase-linear KSD-FIRTEC™ processor, the music signal is converted into sound using the innovative NExT™ technology (Pat.:DE102015102643A). This generates a cylindrical wave that brings significantly more information to the engineer’s ear, allowing exceptional control. The power amplifiers with a system output of >2000W ensure minimal distortion and guarantee unmatched reproduction performance.
Exceptional low-frequency performance is provided by the combination of two sensor-regulated 12“ performance drivers with an additional (vented) dual 15” sub-chassis. The latency-free cone control of the 12“ drivers converts the low frequencies in the music signal into sound in an extremely controlled and resonance-free manner, while the two vented 15” drivers provide the necessary boost, even and especially at higher SPL levels. The combination of NexT™ technology and this exceptional bass drive offers an unheard-of performance with perfect control throughout the entire creative process in the studio.
