At home, I use AirPort Express and AirTunes when using the living room speakers to listen to music. I want to accomplish the same in my dorm room, but I can't bring the AirPort Express at home because my parents need it. This is what I want to accomplish: Use my Logitech speakers and computer speakers simultaneously (at opposite ends of the room) hopefully without wire. Do I need AirPort Express, or can I use some other kind of method? I also am technically prohibited from creating a wireless network w/internet so if this could be avoided, it would be sweet. (a wireless network with no internet connectivity is allowed) Thank You!!
