Dynamic Zero (DZ) is an experimental acoustic system based on a reversible pneumatic architecture, where air is treated as an active part of the acoustic system rather than simply as enclosure compliance or a resonant load.
It was not created as a commercial loudspeaker. It is an open engineering architecture that anyone can build, listen to, measure and investigate independently.
Conventional loudspeaker systems normally absorb, vent or delay the acoustic energy produced behind the diaphragm.
Dynamic Zero began with a different question:
The current 2" implementation is the smallest practical experimental version of that idea.
Its low-frequency behaviour was not the original goal. It appeared as a consequence of the architecture.
The design intentionally uses inexpensive, easily sourced 2" drivers and normal 3D-printing tolerances.
You do not need to accept the proposed operating hypothesis.
Print it. Build it. Listen to it. Measure it. Take it apart. Change it.
Dynamic Zero is published as an open engineering project. The geometry, construction information and measurements are made available so that the project does not depend on claims made by its creator.
Independent builds, measurements, simulations and criticism are welcome.
If you build one, publish what you find. Matching results are useful. Different results are useful too.
Dynamic Zero is an active experimental project. The current design is not presented as a finished or optimised loudspeaker product.
It is a physical architecture that can be reproduced.
