Adding my 2 cents…
Just got a DG212N this week and played out with it last night. I started using an Alpha Omega 500 about a month ago. Holy crap, I love this rig. My band loves me more now too LOL.
For reference, I'm coming from an 80s Ampeg SVT classic with a 410 (sometimes 610 or 810). My usual sound is kind of like that now typical bright and punchy punk sound (Rancid, etc) with a bit of overdrive.
The weight difference between the SVT rig and this setup is obviously a really big deal (no more trying to round up a drunk bandmate to help load out) that could make me tolerate a lot of other shortcomings, but I have found no shortcomings yet. The sound clarity is the thing that stands out the most to me. I often had some trouble with mids getting a little muddy with the 410 (even with the AO head), or losing the low mids in our drummer's heavy use of toms - but neither my bandmates nor I ever really noticed that all the mids could've been more clear until now. But that doesn't mean it is lacking anything in low end, though. The lows do rumble the guts.
On stage, all band members had no problem hearing bass, which I assume is due to the 12" speakers dispersing the sound better than the 10s do.
I originally planned on using this just for the smaller places, but I think the Darkglass 212N will totally replace the 410 for me.
The cab looks really, um, "classy", too, like a nice piece of furniture.
