ESB audio 4.UMA 2-Way Mid-High Unit

- Silk dome 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 N52 neodymium magnet.
- 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 analysissoftware (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. 
- 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. 
- 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.
