First I would like to say that the sound quality is top notch. Definitely worth thirty pounds that I paid for.
Second, the picture does not do justice...the bass is gigantic and emits a powerful sound. The two satellites speakers are not small either. I am sorry but I have not got measurement in handy please do check logitect for in depth detail.
Thirdly, I do not know why people complains about too bassy. There is a separate volume control on the bass and you can turn it off if you want to. Another volume control obviously on one of the satellite speakers.
Forth, A headphone plug on the satellite speakers and a power button. This might be obvious but my previous speakers does not support headphone plug!!!
Fifth, when you turn the volume all the way off, it kills the sound. Again my previous speaker system doesnt...
Sixth, I dont expereince any european radio station yet but why dont you just switch it off once you finish with it? Back to forth point the power button is on the satellite speaker. Turn it off when you go to bed and you wont hear a thing at night. Its good for environment too :)
