Linkwitz Lab
Loudspeaker-design resource preserving Siegfried Linkwitz’s work on active systems, open-baffle dipoles, crossovers and room interaction. It connects technical explanations with named projects such as LXmini and LX521, and distinguishes construction plans and kits from separately supplied turnkey systems.
About this resource
Linkwitz Lab brings together Siegfried Linkwitz’s loudspeaker projects and technical writing on stereo reproduction. The homepage records his life dates as 1935–2018 and carries Frank Brenner’s account of taking over the audio business in December 2017. It explicitly frames that continuation around open-baffle dipole loudspeakers and keeping the website available, rather than presenting every older article as a newly written product announcement. [1]
The technical library covers speaker-design issues, dipole models, active filters, amplifiers, microphones, crossovers, room acoustics, recording and rendering. Its project index includes LXmini, LX521 and LX521.4 alongside ORION, PLUTO and earlier designs. That mix makes the site useful both for studying how a loudspeaker system works and for exploring a specific construction, with electronics and room behavior treated alongside the acoustic hardware. [1]
The homepage directs visitors to construction plans, parts kits and assembled systems through associated supply routes, including LINKWITZ.store and Madisound. It states that construction plans are a required license for purchasing kits and assembled systems. The educational archive, licensed plans and finished equipment are therefore distinct offers. The Basics, Projects and Room Acoustics sections provide clear entry points without assuming that a published design is a self-contained passive speaker requiring only an ordinary stereo amplifier.
