Real deal for sure. I'm a big fan.
I've spent a while with this cab now, and have to say I'm really impressed. I've gigged it with a Tfunk head, TH350, and a vintage bassman 100. Also tried it at the house with a few other amps. GAS killer? I think it might be. I am coming from using an Aguilar DB212, which is a fine cab, but I think I like the Berg better.
I definitely say the CN212 and DB212 are in the same family, but there are some noticeable differences. To my ears, the CN has a little more overall volume - that is, it's louder with the same amp, same settings. The CN is a little more muscular, or beefy, or robust than the DB cab. The DB is no slouch, but the CN just sounds more solid all over. The DB cab, to my ears, had a kind of upper mid range thing that was a major part of its voice. Not in a bad way. It really cut thru a mix,,, but the CN's curve seems much more flat to me. I think the CN has a bit more going on down low than the DB. A slightly stronger low mid voice maybe. More punch, and it just kind of fills the bottom out better than the DB. I also think the top end of the CN is a little more sweet and mellow than the DB cab. (note, that when I say top end, I am probably talking about upper mid-range. I generally don't use the tweet). This has to do with that upper mid thing in the DB cab maybe. Upper notes on the CN cab seem to be there, without even hinting at harshness, and they still have the lower harmonics to make them sound full and deep. The CN just seems to sound confident.
The DB cab is one of the nicest cabs I have ever played, and Aguilar does a FINE job with the cab aesthetics... but overall the CN is the winner in my book. CN took a gig or two to open up, and on the first gig I was a little worried. It sounded a little choked, but once it opened up... dang. I think the Aguilar is prices just a little bit higher, but can be had for just a little bit cheaper. Overall,, Sound + weight = a big win for the CN.
