Maintained! Altec 1.5" ferrite driver. A clear and powerful American sound. The wide-area characteristics unique to Altech resonate comfortably while being rounded and stretched quickly. Both diaphragms have a logo. There is a feeling of use on the exterior due to scratches, dull paint, bald spots, etc. (Asaine Tomoho)
