ESB 9.28 1.1”/28 mm High-End Silk Dome Tweeter

• TCA System for back air flow control: reduces turbulence, noise, and controls the damping of the dome by dosing the passage of the air.

• Body machined from a single piece of ultra-low carbon steel to achieve higher magnetic flux, which means higher efficiency and lower distortion. The large mass ensures excellent cooling.

• Main magnet in F52H neodymium, the best both for the magnetic force in relation to the mass, and for the high temperatures support (of 120° against the 80° of a "classic" neodymium magnet).

• Pole plate obtained with a numerically controlled machine and not by stamping, this drastically reduces construction tolerances to the advantage of performance

• Secondary or superior magnet, used to stabilize and regulate the magnetic flux and concentrate it only in front of the voice coil, increasing efficiency, manageable power, distortion and bandwidth.

• Faraday ring: this copper ring drastically reduces the inductance of the voice coil, in this way the bandwidth of the tweeter can extend well above 25KHz.

• Super light aluminum voice coil. It uses a high-strength aluminum alloy so as to be able to reduce its thickness and therefore its weight. The winding is also aluminum with the "skin" in pure copper. In this way a perfect combination of resistance and weight of the wire is obtained.

• Dome in silk treated with resin.

• Felt ring to eliminate any parasitic vibration.

• Acoustic lens designed to regulate and optimize tweeter dispersion.
