Gold 300 Loudspeaker

The Gold 300 is a three-way design employing a pair of 8" woofers, an unusually small, 2.5" midrange, and a 1" folded "ribbon" tweeter that isn't technically a ribbon: Monitor Audio calls it a "Micro Pleated Diaphragm," or MPD. It's a brother to the Air Motion Transformer (or AMT) invented in the early 1970s by Dr. Oscar Heil. Variations on this design, most far smaller than the original, are now widely used in commercial speakers, though it's still far less common than conventional dome tweeter...
