Anyone know how if there is any way to connect the Apple Pro Speakers to the 2009 MacPro? I am upgrading from a Dual G4 PowerMac, and while I have the requisite ADC->DVI->MiniDisplay port adaptors for the two Cinema HD displays but I am not quite sure what to do with the speakers. There seems to be a product called iFire that is out of production that converts the Apple Pro Speaker jack to fireWire 400. But it is out of production and there is no firewire 400 anymore either, thus another adapter would be needed. I really don't need speakers for my work, but they just look good with the old plastic Cinema HD displays.
