Futurelooks posted a review on the M-Audio Studiophile AV40 Desktop Speaker System

There's a reason why these speakers look so familiar. The AV40 speaker system is the bigger brother to the M-Audio Studiophile AV20 Portable Desktop Speaker System that I reviewed last month. As their names imply, the AV20 came with a pair of 10-watt speakers for a total output if 20 watts, whereas the AV 40 comes with a pair of 20-watt speakers for a total output of you guessed it 40 watts. There is also the Studiophile AV 30. You can probably guess where that fits into the picture.
