KSD Linemaster

The KSD Linemaster sets a new benchmark in loudspeaker design, combining extreme precision with powerful performance. Engineered for mastering and critical listening environments, the Linemaster delivers uncompromising neutrality, phase coherence, and unmatched sonic detail—even at the highest monitoring levels. Thanks to KSD’s proprietary FIRTEC™ DSP engine and the patented NExT™ cylindrical wave technology, the Linemaster offers holographic imaging and precise impulse response, giving engineers complete control over every element of a mix.

Its powerful, sensor-regulated low-frequency system features two 12″ drivers with latency-free cone control and dual 15″ vented sub-chassis for tight, distortion-free bass with added punch. This unique design ensures articulate lows and remarkable clarity across the entire spectrum, ideal for both nearfield and midfield applications. With over 2000W of amplification per side and full compatibility with the optional KSD-RC remote for EQ and room calibration, the Linemaster is a true reference for the modern studio.
