Pipes, tapered pipes and Helmholtz resonators
We've had some discussions here about bass-reflex, tuned pipes, tapered pipes and horns, specifically about their similarities and differences. So I've taken a moment to put together a list of references from authors other than those that normally contri...

Maximum SPL charts
A bass-reflex speaker is unloaded below the Helmholtz frequency. A transmission line is unloaded below its quarter-wave frequency. And a horn is unloaded below its flare frequency. This is particularly true for back-loaded horns, which act very much li...
