"To explain a little more, the purpose of the loudspeaker(s) is to simulate a gas leakage situation in a gas plant."

That's useful info in that we can nail down the crest factor to essentially zero. Unless something goes wrong and there's 174 db peak. Very Happy

Seriously if you need 150 db of the sound of gushing air for say a training facility you probably don't need too much bandwidth, just enough to point out to the trainees that speech will not work.

Most of the time I ask myself questions that I cant answer, so I dig deeper to find a solution only to realize that I know less than I thought I knew.

The SLS LS9900 is specified at 140db, 400hz - 2k 139db above that, enough of them might get to 150db, but stand clear

This is very old thread but no one mentioned a series of speakers from Renkus Heinz. The series is the CEXXX-5 speakers. The come in three dispersion patterns, CE 61-5 (60 X 10), CE 91-5(90 X 10) and CE 121-5 (120 X 10). Thesee all produce levels of about 148-150 DB from 250- 15KHz. These were designed for use in stadiums and large venues where extra control and level made long thros useful. Ray Rayburn used one speakers to cover an entire racetrack in Texas a few years ago. and I have usec them extensively in stadiums and racetracks for long throws of over 800 to 1000 ft.

Four of my TFR's can sustain 150dB at any frequency over 80Hz.
