Loudspeaker Failures and Protections (Part 1)

A new generation of effective and powerful speaker protection technology, using literally all the capabilities and power of pro sound rackmount loudspeaker management processors, is now being designed into mobile audio products that use very small loudspeakers. The implications are that mobile consumer electronics are going to play louder and sound better than ever. But to optimize speakers this way, we need to understand what causes loudspeakers to fail. This article was published originally in audioXpress, August 2013.
