Hello! I was recently given a tremendous set of speakers and I have NO idea what they are capable of. I have attached several pictures of the three custom speaker boxes I was given. They were originally used to amplify an Allan Organ, and are custom built. Basically, I am hoping someone knowledgeable of these products and speaker set ups in general can help me figure out what I have. I would essentially like to know if they can be used as is for something else, like a record player or something. Do I need a receiver, and could I do anything to hook these up together? Or are they only going to work for an Allan organ the way they are set up? Basically, any information you could provide would be incredibly helpful and appreciated, even if it doesn't directly answer my questions above! Thank you in advance to anyone who takes the time to respond!!!
