[ahem, cough -]
I go to bed, wake up, and the thread has doubled in size. Jeeze!
Look - the F210 gets loud. VERY loud. I'm putting 900 watts into it with a Tecamp Puma 900. Turn the dials up and I'm gasping for breath. Even with earplugs, the bass slams into me, knocks me over, and blows the cats out the door. At that level of volume you've entered a zone where many of the tonal nuances we endlessly debate are beyond hearing. We've turned our cab into a weapon of mass destruction where the shear noise level decimates discerning nuances. It now excels at drowning out the guitard.
I used to gig an Eden 410. The F210 seems to get just as loud. Louder? Can't remember. Don't care.
Putting this into perspective, the Eden 410 weighed 100 pounds and was a total PITA to move around.
The F210 weighs 46 pounds. I can practically one-hand it, but I'm older now (and wiser) so I crouch down, and lift it with two hands and my legs. Stick it on my fold-a-cart and it's a cinch to pull up or down stairs.
The F210 has a much smaller footprint than a 410. Fits on a small stage. Holds my amp higher in the air so it's easier to make adjustments than with the squat cube of a standard 410.
The F210 sounds better than any 410 I've played or heard.
Yada yada.
OK, back to practicing. Carry on.
