Selling a rare and hard to find set of four vintage Realistic 40-1390 Advanced Linear Ribbon Tweeter speakers. As part of the Realistic brand, these tweeters are known for their quality and performance, making them a sought-after item for vintage audio enthusiasts looking to restore or enhance their speaker systems. Found these in my Dad’s garage as I’m liquidating his estate. Three are still in the plastic and one does not have plastic covering it but still looks unused. This are very cool and still have the original Radio Shack price stickers and other price tags on the boxes themselves which are in good vintage condition. Very cool find and hopefully they go to a good home where someone can appreciate them for what they are.
