There's some misunderstanding in these posts.
You would be looking for more than the little rectangular device. The Cube's speakers are hard wired into it, with a wire to each speaker and a USB cable in between, which again is hard wired into the device. It is in fact amplifier and sound card, with speakers and all connecting cables, all in one unit designed so that it cannot be disassembled. The whole must weigh nearly 2KG, as the speakers are relatively heavy.
I am not sure whether it only works with a G4 Cube, or with other machines as well, but I suspect that it is Cube-specific. I do know that other spherical speakers of the time that were made for G4 towers and such did not work with the Cube.
An alternative to the stock system is to find one of the soundsticks/isub setups that were sold at the same time as the Cube and that match it nicely, in which the amplifier is (as I recall) in the isub, though there is also an external power supply. I have such a setup connected to a G5 iMac at present, but used to run it on my Cube (with which it ran perfectly) and it was much superior to the Cube's stock sound system. The latter sound system is good, nut not stellar. The soundsticks/isub combo is wonderful. If I were looking to buy a sound system for a Cube, and were not concerned solely to complete a Cube for a collection, I would look for it rather than the stock speakers.
