Thiele Small Parameters – A Quick Overview

We’re still updating and improving these pages, they are intended as general guidelines to help with the understanding of T&S Parameters and their relevance to speaker design. In some cases, a simplified explanation or example is used to illustrate a point, and may not be 100% accurate in all circumstances., BL – Motor Strength or […]

Xlim – Xmech – Xdamage – Maximum Physical Excursion Before Damage

Xlim (also called Xmech or Xdamage) represents the absolute maximum excursion a driver can reach before mechanical failure occurs. It accounts for physical limits such as: Unlike Xmax, which defines the linear range of motion before distortion increases, Xlim marks the point of no return—exceeding it risks permanent damage to the driver. For subwoofers and […]

Driver TS Parameters: Xmax

Possibly one of the most misunderstood parameters, most people know Xmax concerns driver excursion, but dont really know  precisely what it means, and it is probably the name that confuses people, as it is slightly misleading. We’re used to  letters X and Y denoting dimensions, and in this case, X does relate to a dimension, it’s to do with the […]
