I'm a couple of minutes away from getting these speakers for my mbp. I've searched all over the internet, and it seems that the Z-5500's have the best reviews. However, I'm kind of concerned of the 5.1 surround. In better words, I want all the speakers to work properly on my mbp. Do I need anything else to make this work? I will only use this speaker system for music, movies, regular stuff. Sorry if this question was already posted on the forum, its just that I need to order the speakers by tonight. Any response would be grateful, thanks.
