I had a pair of HD112 and swapped them for CN112 many years ago.
The HD112 had a more trad sound. Warmer, slightly scooped compared to the CN112. The CN were more mid pushed.
I really preferred the sound of the HD but the weight saving was considerable.
I wouldn't have either again. HD was too heavy, CN didn't sound how I wanted them to. I've not tried any other Berg cabs. All really well built though.
