Rare Philips pure Ribbon Tweeters, Model RT8/21601 made in Belgium in excellent working and cosmetic condition. Appearance on one has part of silver paint finish missing 1/4 inch long, does not effect play whatsoever, see photos. Reason for selling, used with a Full Range Driver in test and I need a higher efficiency tweeter. These sound wonderful with no issues! I have 100% on Ebay (rsltd) with 241 transactions. Buyer pays all shipping costs including insurance, thank you. $150
