Upon opening the box for this speaker, it is not something to take lightly. The thing weighs almost more than I do, with a weight of 100 kg measuring in at 75x26x24 cm it is not small either. However with its two 25 cm speakers with inlayed 12cm speakers it certainly can make some noise. When in testing the speakers can get up to 110dB easily with no crackling. This deffinitly holds up to the claim that it is as loud as a concert speaker. If this is what she is putting out currently, we can't wait to see what she will be putting out in the future.
