1 Pair Fountek NeoCD1.0 Ribbon Tweeters. These Tweeters require knowledge and understanding of proper implementation. If the drivers are installed incorrectly, damage is assured! TheseMusthave the proper order crossover (LR3), and most importantly, the proper crossover frequency (3,500hz 3rd order minimum). If you do not understand what the previous statement means, THESE ARE NOT FOR YOU! These type True Ribbon Tweeters need capacitors for diaphragm protection. Ribbon tweeters appear as a dead short to the amplifier without the crossover. Always use a capacitor in series while testing or with an active crossover. The Ribbon itself weighs only 10 Milligrams. So, the diaphragm is very fragile, simply blowing on it can damage it. These are some of the speakers bought from a speaker-building company that went out of business years ago. The drivers are new and unused, but the boxes look like hell from being moved around a dusty/dirty warehouse over the years. The drivers are new and look pristine! If you have any questions about the photos, please feel free to ask
