Measuring Loudspeaker Components

A loudspeaker's low frequency parameters can be accurately estimated by measuring individual components without the need to assemble them into a working unit. Using this development approach, much time can be saved by optimizing one component at a time rather than building an entire speaker for each iteration. To do this, one must be able to measure the relevant physical characteristics of each component (the electro-mechanical parameters). It is also necessary to be able to predict electro-acoustic performance from the electro-mechanical parameters.
