Let me just say, having experienced the Bumpboxx and tested it relatively extensively i can state: 1. The Ion thing MrX mentioned, believe me it will not be louder than the Bumpboxx, it would be absolutely eaten alive by it, this thing is serious business. 2. The mono thing, non issue. Honestly i felt exactly the same, then i heard it, it has clarity, warmth and massive bass. 3. It is ripe for customizing, seeing the grills on the one above, great idea.
