Can someone teach me how to read the 20Hz curve on this graph? Why the hack at any measured level there are two correspondent measured distortions?
To me it looks like some kind of protection mode kicks in as you get close to 200W. That's what gives you the weird extra "backwards" line.
Noise dominates all the way to ~70W, and distortion only takes over with a dB or two until you hit clipping at 123W, and then starts to skyrocket.
