From what I remember, 410 NEO sounds a bit more scooped and a bit more hi fi than 212 (and 412). The 12'' neos IMO have warmer low mids, and more balls in the mid area. I have no problem getting tremendous low end from my cab, especially when I kick in the synth pedal and start the frequency sweep. Or Swollen Pickle that has tremendous low end! My 412 was shaking the floors with the Pickle low end, and definitely threw more low end than my old Ampeg 810. The low end really opened up on my 412, and it's fabulous. Never muddy, and gives such a nice bottom.
