I need new speakers for my MacBook Pro. I'm looking for something $40 - $60. I have two different models in mind. I'm thinking of the JBL Duet and the Logitech X-230. While I want bass, it's not the most important thing. If the JBL Duet offers signifcantly better sound, then I will go for the Duet's sound over the X-230's bass.
