The one disadvantage of the Neo 212 is the 8 ohm load, and not getting the full potential from the amp. The TBers above that have had experience running out of steam, I would ask for what the weakest link was in their experience?
The GK1001rbII or the Neo 212....?? Did the amp run out of headroom or did the cab start giving up? This might better help you determine if two Neo 112s at 4 ohms will be enough.....etc
Should get quite loud, but everything is relative......
Tom Bowlus has gigged with Neo 212 and Neo 112 stack with GK 700RB I believe....seemed to be quite impressed.....
If 2x Neo 112s is doubtful, then maybe 2x Neo 212, or a 4x10 or two. At this point, you are talking about some serious volume....
In either event, if you can control the lows and dial in some low mids and mids, you should be able to push some sound...and be heard....
Personally, its been a while since I gigged with a GK1001RB. I currently use MB LMII and Berg cabs.....but I am hearing really good stuff about the GM Neo stuff.....
Good luck
