One advantage of the Genz Benz Contour combo, over some other combos, is that the speaker is connected to the head with a proper Speakon connector, which means that should either the head go wrong, or the speaker, then you can still connect what still works to something else. The head also, though not designed to be removable, seems to be of the fully enclosed metal chassis type so could, in a pinch, be taken out of the unit (and used standalone or sent away for repair). Obviously not as flexible as a proper detachable head combo, nor as flexible as a separate head + cabinet, but for the money it's a great package.
