YES! that's the final plan- another r210 cab totaling 410s, but you maybe right about headroom; thanks.I have a feeling you will be more impressed with the 200c/210 than just more watts going to the 210. 350w going into 210 is probably not really going to do more than 200w also pushing the 15. Though it might be close, I think most would agree the more speakers is going to make more difference than more watts, though you might have to run towards the top of your headroom.
Now a 500c on a 210 might be a different story, but as you know, the 200 is quite surprising
