Well, if in case anyone was counting, the RMS rating of the ATP-3 is somewhere around 50W with the 6.5inch subwoofer itself punching out 30Watts of RMS, while that of the Creative 4400 is just 43Watts or something with the subwoofer rating of 17 watts. There is no comparison here other than that of the 4.1/2.1 issue.
