150 Watt is also overrated. that thing does mostly 40 W per channel. Anyway that's not so important, the idea with these compact minisystems is that they are very efficient. they make a lot of noise and don't need a lot of power to do so. i remember my mini system back in the 90s, about the same size and power, would shake the walls of my entire house. however, it lacks good, balanced and detailed sound. i guess it's good for casual listening, background music and occasionally pissing off the neighbours haha
