Thank you for your explanation of 'stereo' sound John C.
This subject came up at our Club recently as someone had seen the new Bose being used at the local Organ Club but he couldn't explain how it worked without speakers. Although I had some idea, as a few years ago I used 'amplified speakers' which were good but I couldn't explain how they worked, let alone the Bose, so I will pass on your detailed explanation to our members at the next meeting.
