About LNGR SPKR
A private DIY loudspeaker and engineering notebook focused on transparent assumptions, measurements and iterative development.
What LNGR SPKR is
LNGR SPKR is a private DIY audio project by Florian Langer. The site documents learning, modelling, construction and measurement rather than presenting finished products as immutable recipes.
Method
Start with the engineering model, document assumptions, build, measure, listen and revise. Planning states remain visibly versioned so changes are traceable.
Scope
The main focus is loudspeaker and subwoofer design. Selected off-topic DIY projects are included when their documentation, CAD or construction workflow is useful in the same maker context.
Technology from Dortmund
LNGR is an independent DIY technology project from Dortmund-Lütgendortmund, focusing on loudspeaker development, audio technology, electronics and technical learning resources.
