Thiele/Small Parameters Explained: How Subwoofer Specifications Predict Real Performance
Thiele/Small parameters are a compact mathematical description of a driver near small-signal operation. They allow enclosure behavior to be modeled, but they do not fully describe high-power heating, excursion compression,...
