ESB Audio 3000 Series 1" Dome Tweeters
ESB Audio 3000 Series 1" Dome Tweeters
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
- The tweeter features 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. The dome is of extremely low mass and is much less susceptible to mechanical deformation than other tweeters, yet provides a smooth, linear and very extended response.
- The 25 mm voice coil has an aluminum support and very light copper-coated aluminum wire. The voice coil is ventilated and damped with iron-fluid oil.
- The special SVS ventilation design provides two benefits: optimal cooling of the voice coil and avoiding compressing the air at the back of the dome.
- The neodymium N42 magnet, a type of magnet with significantly higher performance than "standard" magnets, is optimized with computer simulations to get better efficiency and improve linearity.
