I know this sounds like an idiotic question, but surely you can agree that it makes sense to assume that a $120 set of speakers have a higher sound quality than $16 speakers. However, after doing some reserach, it seems as though the wattage of a set of speakers has nothing to do with sound quality. If that is indeed true, then how do you determine the sound quality of a pair of speakers? Specifically, I would like to know if the $120 speakers linked below, have a higher sound quality than the $16 speakers also linked below.
