SPL vs. SWL 

As the article starts out mentioning, SPL means Sound Pressure Level, whereas Sound Power Level is abbreviated SWL. So correct me if I'm wrong, but when speaker manufacturers mention 93 dB SPL 1W/1m, are they not referring to Sound Pressure Level? In that case, this section should be in the Sound pressure article (which details SPL), instead of this.130.227.121.251
