There are several simplified articles on loudspeaker operation and their inherent physics that we could suggest for reading through an internet link. However an average hifi enthusiast reading our tutorial articles on speaker design framework would fail to follow their content and to understand them. Applying blind design instructions is always feasible but we do not wish to choose it. Eventually we created our own series on loudspeaker physics.

The article series that follows needs patience especially when new physical quantities are introduced or equations are presented. As these articles advance reader will gain some knowledge to handle loudspeaker parameters and to understand how they affect speaker design steps.

Try not to skip any of them as they all include information needed later on.

Context presented:

  • introduces basic loudspeaker operation and parameters,
  • gives a rough idea of rear-side radiation in various speaker types,
  • covers the Closed- and Vented-Box speakers in detail,
  • explains how front-side loudspeaker radiation is distributed in space at a certain distance, on and off axis and finally
  • attempts to resolve the anomaly in SPL responses of everyday speakers, known as 'Baffle Diffraction Step' which is caused by the rectangular shape of cabinet baffles.

We are open to any complaints or suggestions for editing, rephrasing or major restructuring of any tutorial article. Our intention is to make them as efficient as possible.
