I seem to remember ASC saying on their previous website at EC1-EC12 ranged from 121-128 decibels.

I honestly doubt even the largest models are over the low 120s in real life. I haven't heard one in person, but I have heard the equivalent model ATI, iForce and Allertronics. Definitely not a "knock your socks off" product. With the exception of the Whelen rotating sirens, most electronics are better utilized for small/local area PA and warning. A modulator makes sense in an industrial application or at a university. They do not make good large-scale community warning systems...unless you're Moore, OK and put one in every other block.

Our E-classes are pretty decent, then again they play a recording of a Tempest over them. I'm sure that plays into it.

There are two units in Cincinnati. The one on Paul Brown Stadium has all four speakers pointed east, which should be a pretty good output for that direction. The one on top of the US Bank Arena garage has the four speakers pointed randomly in the southern 180 degree range. Should all be good enough for that section of downtown.
