The Wall of Sound iPod Dock is perhaps the coolest speaker innovation to date. It is big (3ft x 4ft big) and it produces massive sound with stellar visual appeal. Plus the best part about the Wall of Sound iPod Dock (aside from being Swedish-built), is that you can that it produces a massive wall of sound to all your friends.
Implications - Tech junkies are looking for either the biggest possible gadget or the smallest possible gadget. Other industries (besides technology) can play with size and volume, which will appeal to younger consumers right off the bat because of the sheer visual aspect of the extreme difference in proportion.
