While it might be possible to attain stated max levels from that box, it'll probably only happen once... and it might catch fire.

Chapter 3 of 4 in the new Biamp Expert Series on Loudspeakers, entitled “Spec Wars: Looking Inside Loudspeaker SPL Specifications,” is now available for free download (below).

The past decade has seen a significant rise in the deployment of active loudspeakers, mostly 2-way designs housed in molded plastic cabinets. With modern processing and plenty of class D power, it’s possible to get remarkably good sound quality from these lightweight models.

They will also go surprisingly loud, with manufacturers routinely claiming in excess of 130 dB from a single loudspeaker! With that in mind, let’s take a closer look at some of these claims and examine whether they’re plausible or indeed possible.

There will also be some tech talk, mostly relating to loudspeaker cones and what happens when feeding several kilowatts into one.

The Expert Series on Loudspeakers is presented by Biamp and features top authors from ProSoundWeb and Live Sound International magazine.
