That rating for the Logitech would be PEAK power, its real RMS rating(115 is approx the Bose RMS figure) would be around the 220 mark.

The Bose would be a much higher quality than the Logitech, in both build and in the quality of its audio.

One of the great marketing tricks is to quote peak power figures, which whilst true are very misleading as to the continuous power input.

And just for those who are not aware 'PEAK' power is the amount the unit can put out in a very short bust when the input signal gets too high. But if a user maintains that level for any length of time, it can be bye bye speakers.
