Selling a vintage 1974 Advent tweeter, known as the 'fried-egg' tweeter because of its appearance. Removed from one of 'The New Advent' speakers (circa 1974). Two are shown in the pictures, but one does not function. Asking $25 for the good one; the blown one is included as well. Accepting offers. I have no more Advents in my collection, so maybe someone can get some use of the working one. Will ship by mail/post for $40 all in. Jeff in Peterborough.
