Ok. So I've tried searching around and I've found a few options but most products like the Griffin FireWave have been discontinued. So I'm looking for something that could convert my Logitech X-530's to my MacBook Pro. It uses the three cables (green, yellow, black). Considering these speakers aren't that great. I don't want to be spending hundreds on a converter. If it comes to that, I'll just purchase the Bose Companion 3 or something.
