ESB audio 3.UMA 2-Way Mid-High Unit.

-This special and exclusive component driver is a concept conceived way back in 1970’s.
Its aim is to concentrate medium and tweeter emissions in a single virtual point.
This minimizes phase delays and irregularities at the crossover point.
- The neodymium magnet is high grade type to eliminate magnetic losses at elevated temperatures and to concentrate more force in less space.
- The tweeter has a silk-impregnated, thin fabric dome diaphragm for a smooth sound, with an outer suspension covered with a high-loss damping material to eliminate edge vibration and resonance.
- Pressed paper cone with waterproof treatment (midrange) for the ideal marriage between lightness, stiffness and the ability of the cone to dampen any  unwanted vibration.
