ESB Audio 3.UMA Midrange/Tweeter, 2.5"/65 mm Mid + 1"/25 mm Tweeter (pair)
Main features
- This special and unique component element is a concept designed already in the 1970s. Its objective is to concentrate the mid and high frequency emissions in a single virtual point. This minimizes phase delays and irregularities at the crossover point.
- The neodymium magnet is of high quality to eliminate magnetic losses at high temperatures and to concentrate more power in a smaller space.
- The tweeter features a silk-impregnated thin fabric diaphragm for a soft sound, while the outer suspension is coated with high-loss damping material to eliminate edge vibration and resonance.
- Pressed paper cone with water-resistant treatment (midrange) for an ideal combination of lightness, stiffness, and the cone's ability to reduce unwanted vibrations between.
- The voice coil uses an aluminum support and a double-layer winding technique with copper wire on an aluminum core.
