Siegfried Linkwitz is a well known reference in the Audio industry. His work range from filtering to speaker building and has been referenced/used by many designers worldwide for the past few years. The Linkwitz Lab website is a goldmine of information on advanced filtering, speaker building and even basic concepts of acoustic and speaker design. A reference website for any audio designer!

The latest addition to Linkwitz Lab portfolio is the LXmini, an alternative to the Pluto 2.1 design and built around a miniDSP 2x4 platform. Fully engineered by Siegfried himself and his legendary handmade pole/zero diagrams, this new design is yet another

The LXmini is a most remarkable loudspeaker. It converts electrical signal voltages into acoustic pressure variations, which are perceived as completely neutral and detailed even in a reverberant environment. With this design I want to give every music lover the opportunity to build and enjoy a reference quality sound system singing in their own living space.
