Logitech R-20 Total RMS Power 12 Watts Subwoofer 6 Watts and Satellites 6 Watts Total Peak Power 24 Watts at less than 10 % THD I don't really know what that last part means but that what is listed under specs.
It means 10 percent Total Harmonic Distortion at a frequency of 100 Hertz, basicly good undistored listening at low to mid level volume. ITS NOT for a party!!
