Small vs Large signals often refer to the input voltage (small eg from Bluray player or preamp) vs the output voltage from amp to speaker (Large).
In this context, small signals would be those that don't induce power/excursion related distortion. The driver or subwoofer would show a linear response at .5w, 1w, 10w. Distortion isn't appreciably changing.
Large signals are where the rubber meets the road, if your application is SPL-limited. 100w, 200w, 1000w, etc. This tells you, how hard can I push this thing?
So a Frequency Response graph showing great extension to 28Hz can be misleading.
Like, "Look how I can lift this ruler with speed, control, acceleration. I made a graph, even. So, you should extrapolate that if we give me a broadsword, I will swing it the same control and speed. And a 200lb dumbbell, too!"
In reality, we know it's BS and only Hulk could swing a dumbbell like it was a little ruler.
