Unlikely. Big, insensitive, many-driver speakers in a very large room may require hundreds of watts on peaks when playing well-recorded material with a wide dynamic range, but most speaker systems in more common residential rooms seldom require more than a couple of watts for an average listening level in the 80db range. Peaks that are 20db higher than that might require 200 watts for some number of milliseconds, but I'm a skeptic even about that.
