Sold Bulk - No retail Packaging Comments: This listing is for ONE PAIR of horn drivers. You get TWO(2)! This is an aftermarket piezo horn driver that's designed as a replacement for the vintage Motorola KSN1142A. It's about as close as you will find to an original without the huge price. It fits standard pro horns that use 18TPI screw-on threads. It's a popular super tweeter driver often used in pro, car, home, and studio speaker applications. 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 also use multiples.
