These tweeters are best suited for custom installations, where brackets are not needed * As pictured, each tweeter is mounted on a coaxial arm, which would have mounted it in the center of a coaxial speaker * Tweeters purchased will ship as shown, with no other parts, accessories or retail packing * If you have the capability of installing them, or making your own installation hardware, they are a Great Deal * Installers will find it ideal to mount these in factory location, using their own mounting hardware (even hot-glue)
