There's no law making it illegal for you to install a sound system that can produce 200dB SPL in your home you're just forbidden to produce higher SPL's in public.
In any way this is all marketing. Of course Devialet isn't specifying a continuous 4500W power output as that would indeed require 4500W of power input PLUS conversion losses. Power can't be created out of thin air. The figure must mean some peak power output for an unspecified amount of time (probably some milliseconds).
Same goes for the Experts, there's only a 600W or so PSU inside the 800 so it's not capable of sustained 800W output levels, again perhaps during a short time only using PSU/capacitor stored energy or even shorter from mains.
It's all a bit foolish though, I thought the industry had left that wattage race behind them. Not even cheap PC speakers boast idiotically high PMPO power output figures anymore like in the early nineties and switched over to the standardized RMS spec. I guess it must still win over some uneducated buyers who get easily impressed by these numbers and like to brag about it among friends at birthdays or in the pub.
