Which speakers do you think would go better with an iMac? Logitech Z-4i JBL Creature II I like them both, and they are about the same price. The JBLs have a treble control whereas the Logitechs do not (to my understanding). So which do you think would go better with an iMac? Also, there are green LEDs under the white JBLs. Is it possible to replace those with a different color? I don't really want green.
