Not sure if this helps or not, but I have experience with similar products. I have an older (black grille) Super Redhead, and I had an SWR 350 head and a Son of Bertha 1x15 cabinet that I occasionally used together at rehearsals - sort of the Black Beauty in component form.
I've always loved the sound I've gotten from the Redhead, but I was never happy playing the SOB by itself. I've played other single-fifteen cabs that I've liked much more than the SWR. It went deep, but wasn't ever of much use by itself in a rock-band setting. I always felt inaudible standing near the amp, though listeners never had an issue hearing anything.
The Beauty may be voiced a little differently (probably not by much), but I felt the Redhead was a more useful combo for playing with others.
