I have aquired a dozen bose 70v speakers from a commercial remodel the speakers worked when we removed them and look brand new is there any cheap way to use some of them in my garage and how much would an amp cost approx
All you need it a 70 volt amp with the proper output if the transformer is built into the speaker. Nice thing is you can daisy chain these. You do not have to worry about a series/parallel circuit or have a home run to every speaker. You will have to spend a minimum of about 480.00 on an amp to do this. You could find a used one as well more than likely on ebay or some other site like that. Feel free to ask me anything else that you have questions with.
