ESB Audio 3000 Series 2.5'' / 1'' UMA
The ESB 3000 speaker system was developed and assembled with a great commitment to the research of materials and engineering solutions of the highest level.
The baskets have been engineered to obtain maximum torsional rigidity (resistance to bending). The speaker cones use pressed paper with a waterproof treatment which represents an ideal marriage between lightness, stiffness and the ability of the cone to dampen any unwanted vibration. All the woofers are equipped with a Y-35 grade ferrite magnet motor, having significantly higher performance than classic "standard" magnets.
The tweeters use a silk-impregnated, thin fabric dome diaphragm for a smooth sound, with oversized voice coils ventilated and damped with iron-fluid oil.
They are supplied with accessories for flexible installation.
Main Features
- 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.
- The voice coil uses an aluminum support and a double layer winding technology of copper wire with an aluminum core.
