Gold ribbon Cocepts in the 80's used a somwhat similatar though - vertical oriented magnets left and right in front and behind the ribbon. Their real innovation was to use vapor deposition of gold on a Kevlar membrane to get the impedance high - very thin coating. 4 ohms over 8 feet of ribbon conductor.
