CJ,

: The human ear needs an increase of 3dB to obtain a noticable difference in volume…

Not so. Listeners usually report that a 3dB increase is "twice as loud". The human ear can actually detect 0.1dB differences in volume. The remainder of your calculations are correct as is your conclusion.

Everyone interested in this topic of how many watts are needed should read Brad Meyer's article on the main SMR Home Theatre site, the link to which is at the foot of this message.
