Особенности

Оригинал (English)
  • Silk dome (tweeter) with polymer laminated (Sonatex™) creates a perfect balance between weight, rigidity, and self-damping. The catenary curvature ensures wide dispersion of the tweeter.
  • High-grade neodymium magnet. Not all magnets of equal size are equal in strength. This high grade (N52), high-energy magnet provides a high resistance to demagnetization and is over 25% stronger for the same mass than more common lower grade magnets.
  • An acoustic resistance component inside of the ventilation hole helps to control and dampen dome movement resulting in reduced distortion and a linear impedance curve for improved speaker/amplifier coupling.
  • Ultra-low carbon alloy steel pole piece CNC-machined magnet analysis software (FEM) to create a perfect geometry.
  • Long-fiber, unbleached pulp cone (midrange) with a special external treatment that makes this material a perfect combination of lightness, rigidity, and internal damping. Discerning audiophiles consider pulp to be the best compromise for a speaker cone reproducing low and medium frequencies. The curvilinear-shaped cone improves this speaker’s performance through their unique geometry. The sensitive inner section at the cone features a severe angle design that aids in its performance. The outer edge is flat and more rigid, producing louder mid-bass frequencies that radiates uniformly throughout the listening environment.
  • The voice coil is designed to be extremely lightweight in order to easily reach the highest frequencies, but at the same time, remain durable enough to handle great power. The copper clad aluminum wire voice coil is very lightweight and with excellent heat dissipation/capacity. Copper is coated over an aluminum surface providing equal copper surface area at a fraction of the weight of solid copper wire.
  • Injected ABS twin frame. This custom configuration is what has made ESB famous in the automobile audiophile world: the UMA unit ("Unità Medio Alta" in Italian). The extremely close positioning of the midrange and tweeter emission centers make these two components virtually one, facilitating installation in cars where space is tight and the separate position of these drivers would create quite a few phase problems.
  • Deluxe protective stainless-steel grille with perforations calibrated to function as an acoustic lens, guaranteeing the sound emission will be in the on-axis part of the speaker.
