why do my $40 logitech speakers sound better than my $120 edifer speakers?

all i use my speakers for is just tv, like news and such, cnn, ect ect, my logitech 40$ speakers have a more balanced, "flat" sound (if thats the right term to use) the treble and bass sound like its one blended sound, with the edifer speakers, i can hear the treble and bass, are "separated" and for tv viewing it is distracting and does not sound natural,

am i crazy? or is there a reson why i think the logitech is better for tv/voice listening
