Loudspeakers not microphones?

Another tool used by the fabricators of these hoaxes and calumnies is the distorted fact. It has been said and written that there are “concealed microphones” in Villa Tevere. There are loud-speakers, not microphones, which are not concealed but clearly visible, installed, not in small rooms or offices but in big sitting-rooms, the laundry and in one or two oratories. They can be seen by anybody. Their purpose was to enable Monsignor Escrivá to lead a get-together or give a meditation with big groups of his sons or daughters in the Work. They were used two or three times on family occasions or celebrations to send Christmas wishes, to ask what presents they had had for Christmas, or to have them hear some songs.
