The CDT-3800-C features a 1-inch aluminum tweeter mated to a swiveling 100-degree Tractrix Horn. This swiveling horn design dramatically increases efficiency by enabling the speaker to produce more output using less energy. Additionally, a horn-loaded tweeter works well in instances where you want to point the sound to a specific location because it has more controlled directivity than a conventional dome tweeter.
