the foil is conductive. Not sure. The 20.1s and 3.7s I've heard had a really sweet top end. The earlier "dot ones", however, sounded to these ears like a collection of separate drivers.

That's exactly correct. With the true ribbon tweeter, the radiating diaphragm is also the conductor. It's about 5 feet long and about 1/4 inch wide, and is extremely light and thin. It's aluminum foil that is significantly thinner than kitchen-type aluminum foil. The electrical contacts are at each end, but there are small, alternating supporting dots of silicone rubber along its length on each side attached to the magnet structure. The resolution and inner detail in its range are marvelous.
