the lie already begins with the idea that more power consumption would be something good, because a good quality loudspeaker is distinguished by a high efficiency. (naively put: pressure per watts @ frequency range of n to m)
i guess it is the same for vacuum cleaners, but there it is only interesting in order to save energy.
the average earth inhabitant probably still thinks that electric machines would
produce power. "that speaker makes 1000 watts!" no bud, it eats them up. often for nothing.
this small $350 set "has" 1000 watts, if you believe their advertising.
i can assure you that you can destroy it by feedign it more than 250 watts after only 10 minutes.
this bigger set of stereo speakers, which were around $3500, is the one i use in my living room. they are roughly around 300 watts per speaker, and at full power they literally blow your mind in a small room... between 10 and 30,000 Hz, btw., while that "hi fi" kind of "cinema" nonsense kind of only gives you mids.
and this is not even professional high end gear - not at all. (unfortunately they are very noisy, whatever the good power2pressure ratio they might have.)
if my non-musican friends ask me if they should buy some super hifi nonsense from braun or rather from teufel, for listeing in the same sitting position, i point them to a pair of yamaha NS-10 from 1980, which cost 50 euros and are at least as good.
