This is a very popular super bullet piezo horn tweeter often used in pro, car, and home audio speaker applications. This tweeter has a unique optional feature that some may like. There's an extra terminal on the back that connects to a LED in the center bullet. Simply jump a lead from your positive terminal to this and when there is enough volume the led light will flash with the music. But note: The led does NOT need to be connected. Because of its piezo design it provides clean crisp highs and doesn't require a crossover making it easy to wire. You can simply connect these to any existing speaker outputs and even use multiples. They make a perfect add-on to any audio system making it sound cleaner and brighter. Also an excellent replacement for home cabinets and it works great in car speaker boxes as well. One of the best, easiest, and cheapest things you can do to improve the sound of any system is simply by adding a set of tweeters.
