If I feed it (what's needed for) 100 watts of a 15Hz sine will it play it (even at -xdb depending of it's high pass) or is just academic?Wot's puzzling?

If DC is bad then why amplify it?Impressive that is apparently switches between ranges of operation good and bad.
Because you have DC response by default and need to add components to have a high pass.Then why have DC response if it’s limited? Does the amplifier enters protection at 20kHz?
I must admit I'm as confused.If I feed it (what's needed for) 100 watts of a 15Hz sine will it play it (even at -xdb depending of it's high pass) or is just academic?
I did some quick and fast developmental ideas and considered the speed and decided that this stuff is amazing.If DC is bad then why amplify it?
Besides, where do you see the activation speed of the protection circuit?
I admit it's confusing the way I asked.I must admit I'm as confused.
"What puzzles me is that they state 3Hz at 10 watts (-3db) but 20Hz-25Khz at nominal power."
I've never seen that before but the other stuff looked OK. I am interested how you are confused. LoL.
I understand but you have not answered my question: what does that DC response offer if it can’t be utilised fully to the amp’s spec?Because you have DC response by default and need to add components to have a high pass.
The protection is to ensure that supply rails are not shorted to the speaker. There is nothing to be avoided at 20 kHz.
Show me the stuff. Ima sure there will be many that want to pipe in on this one.I admit it's confusing the way I asked.
So:
They state 3Hz lower bandwidth but only at 10watts of power.
They state 20Hz at nominal power (1200 watts).
Is that (the reduced power even if they state that that 3Hz is at -3db) because of the high pass or just a measurement condition?

What am I looking for?The PDF is here:
1200AS2 - ICEpower
The 1200AS2 combines a single stage PFC converter with a 2x 1200 W high performance, ICEedge based class D amplifier. Besides extreme audio performance and power it also features monitor outputs for amplifier temperature, voltage and current output. The DC hanger bus can be used for powering...icepoweraudio.com
About 11 page are the full specs.What am I looking for?
Okies. I have it opened what have you in mind?About 11 page are the full specs.
If you can decipher ,if it plays that damn 3Hz even at -3db at any power or not!
What I've ask in my previous post.Okies. I have it opened what have you in mind?
Yeah, and if you do so what? No need for a such a low Ohms driver amp then.What I've ask in my previous post.
Because if it DOES reproduce all that below 20Hz I'll high pass them to the ground,I don't need them,it will be a waste of power plus my woofers will be much happier.
But the topic is DC response…About 11 page are the full specs.

The thing we have ongoing here is the power transfer between the input DC?AC power and the PWM DC power +/- output and what is considered a short for the amp and at what frequency is the rise time too much and drains the power supply smoothing caps.What I've ask in my previous post.

DC or thereabouts as the title of the thread says.But the topic is DC response…
A image from a O-scope would be very useful in estimating the calc.so -- maybe I am naïve (me?!?), but the pulse width for reproduction of DC by PWM ("Class D") would be very wide, wouldn't it -- or very narrow?
