Harman/Kardon SoundSticks II
These "sleek and sexy" Harmon/Kardon speakers (and subwoofer) weren't made just for Macs, but they look so good they might as well have. I won't pretend that I know anything about what makes a speaker system good or bad, but most reviews say these have a gorgeous, sharp sound. And I like the way they look. So, since the speakers that came with our Mac are partially dead, these are my choice for replacements.
