According to the Frequency Spec. they are fine. However, I would not recommend these speakers based purely on the auto-off function.
The auto-off function makes them frustrating for regular / PC use. They are good if you want to play a continuous series of sounds (e.g. a movie, or a playlist), but not good for intermittent sound because the speakers switch off automatically. After they have switched off, they switch back on when the next sound is needed, but after an initial delay >> frustrating.
Also, your input device (e.g. your MP3 player or computer) must have the volume set quite high, so that the speakers do not switch off even when in normal use. You have to set your device volume very high, and your speaker volume low.
