High performance yet small speaker for the small engines in our collections.  I use this speaker in 0-4-0 steam engines, RhB tractors and other engines where the other speakers don't fit.  The cone is a metal film and I am always amazed at the sound of this tiny speaker.  Of course I prefer the large speakers but when you pressed for space this is a good alternative.  I easer glue or screw these speakers into position, depending on the engine type.
