Speaker Design: Driver-Induced Vibrations

In order to generate a sound, a driver must vibrate. But what happens when one or more drivers are placed on the same baffle? In the exact moment that the cone begins to move, it starts to transmit — through the frame and the screws — vibrations to the cabinet and to the other drivers that are fixed on it. This article discusses multiples approaches to handle the problem, working on material, dimension, thickness, density, rigidity, and damping of the panels to be used.

An excellent article from the audioXpress archive, published originally in February 2003, James Moriyasu offers a complete study examining speaker cabinet edge diffraction and what we can do to reduce it. The author attempts to measure the extent of acoustic edge diffraction and test possible solutions for reducing its levels
