"Actually it doesn't, as those things are shipped via container by the thousands, fully assembled - which means you pay by volume, not weight. Most of those speaker-docks are manufactured in only a couple of factories in asia, where products of various labels run from the same production line."

"I worked for some (not to be disclosed) consumer electronic companies, especially in the field of iphone docking stations and speakers. Most new small speakers work with very light neodyme magnets instead of the old heavy iron magnets - which makes no difference in sound quality at all - but they feel very light and less worthy. So, to compensate, we have to screw a steel backplate into the wooden housings to keep the feeling of quality by weight, which is a big, BIG factor in the audio sector."
