I do watch a lot of movies and TV shows on my iMac so the loss of bass is a bit of a problem with the new machine (when I actually get it!). I was wondering what everybody was going to do about this? Should I get an external speaker system or should I just go for something like this? http://twelvesouth.com/products/bassjump/ The price seems okay. 100 bucks is about the most I'd want to pay for speakers.
