*One for ribbon tweeter, one for midrange (2½ A for each)

Right/Left speaker identification
From model MG I to model MG IIB Magneplanar specified the speaker side (right or left) because of different driver arrangement. The red arrows in the pic below indicate the tweeter.
A partire dal modello MG I fino al modello MG IIB, il lato destro o sinistro dei diffusori è specificato. Ciò in ragione di una diversa disposizione dei driver. Le frecce rosse nella figura sottostante mostrano il diverso posizionamento del tweeter.
