I discovered these speakers built into the wall in our house, with the cabinets extending into an attic space. The cabinets are a nice mahogany or walnut or similar finish. There are no identifying marks on the front of the speaker, and in the attic where the cabinet is it's very dark and dusty. Our house dates back to 1961 so I imagine the speakers are of similar vintage. The one in the photo is missing one bass driver, and the other bass driver's surround has decayed. I'm sure the other speaker is in similar shape.
Any thoughts on what these speakers are and whether it's worth hunting down replacement drivers? A friend thought they were Altecs but not sure. Thanks!
