So that odd, I was told it was one 400 amp driver, but I see here, it (4) 100 amps... :?

Well now wait a moment. The amps and drivers are two entirely separate things. The amps exist as part of the controller, while the drivers exist as a part the speaker array. In fact, the drivers are the speakers.

Thus the driver does the actual noisemaking. The amplifier boosts the output of the audio signal from a weaker production source (the tone generator) to something much larger (high power speaker drivers).

A 400 watt amp can power four 100 watt speakers. This is exactly what Federal does with the UltraVoice (and I'd assume ASC and ATI with their controllers as well).

With a Whelen product, one 400 watt amp powers one 400 watt speaker driver. Still entirely acceptable.

Now I'm no electronics expert, so my explanation may be slightly mangled. I'd have a look here for more info:

You might be surprised where that AS100N driver is made, I am almost positive Taiwan R.O.C.

It could have been a change, or any of a lot of explanations.

The E-Class is ASC's cheapest siren. The I-Force model is much more expensive. I've always thought the E-Class looks like an ATI. I'm pleased that I was'nt the only one that thinks so.

Wait a minute. Is the E-Class cheaper than the T-128?

The E-Class is just a few speakers mounted to a metal bracket. The T-128 on the other hand, has a motor and chopper which the motor is quite expensive and the chopper takes time to make. Plus the T-128 has a housing and the E-Class does not. That's the reason why the E-Class is so cheap.

Keep in mind that the speaker shells on the E Class are from a Chinese manufacturer that also makes them for ATI, so ASC barely makes them other than the controller and mounting bracket.
My knowledge excels on the Federal Thunderbolt siren and SiraTone EOWS sirens. ¯\_(ツ)_/¯
