I had an aha moment the other day. Has anybody used or even compared these two bass heads yet ? I'd like to know how they compare at 4 ohms. They are both rated at 500 watts @ 4 ohms. Each of them may well represent a different era of smaller bass heads. We know they have different features. Since Eden has released a whole lot of bass heads - curiously, let's consider their newest offering - WT-550. How do they sound through the same cab ?
