I've come into possession of a B&O Beomaster 1600 receiver circa 1980s.
I've basically just use it as a radio, but I do think it among the most interesting and cleanest B&O designs.
See attached photo.
The photo also shows a mock up of a little project to add a pair of speakers in the same style as the Beomaster receiver.
I can manage the fabrication. It will take some careful and detailed work, but I've got lots of time during COVID.
As you can see in the attached (upper right hand photo) of the side view of the receiver, the front of the device has a 2 inch height and the back of the device has a 3.75 inch height.
I can make the width of the speakers anything I want (maybe some Fibonacci proportion) so I have flexibility in the width.
Device specifications:
I'd very much appreciate recommendations for a driver that could fit in the form factor, within which I have to work.
