My AccuGroove Bill Dickens Signature 2X12 arrived today. My first impression is that this cab lives up to the hype---solid, tight, bottom which welcomes a low B; flat frequency response that accepts EQ very well; smooth, clear highs with no hint of harshness. My only problem is having to survive the 4-8 hour break-in at "low to moderate volume" before I can turn it loose. I have tried MANY major speaker brands in many configurations, and nothing I have tried approaches this cab. And it's built like a tank.
