Sorry to be rude, but the clip sounds EXACTLY like my MG50DFX
That is 100% clean channel on the Splawn. The gain boost is from the Treble Booster.
This speaker, simply put, will not break up and no matter how hard I hammered it, never got brittle, spitty, chuffy, wooly, or any other negative side effect I've had from cranking a single 12".
