Eighteen Sound HD1050

The compression driver with 1 ″ output Eighteen Sound HD1050 is designed for use in high quality audio systems. Equipped with Eighteen Sound's proprietary Phase Plug architecture, the HD1050 guarantees high reproduction uniformity and a consistent and uniform wavefront.

First of all, the power factor corrector, with its small openings, ensures low distortion and shows significant improvements in the reproduction of medium-high frequencies. In fact, the diaphragm assembly is composed of a titanium dome inserted in a group of treated polyester suspensions. This maintains a low resonance, lowering the minimum crossover point value to 1.40 kHz.

In addition, the aluminum moving coil with EWAL (Edge Wound Aluminum Voice coil) winding, wound on a treated Nomex support completes the diaphragm assembly. Thanks to its physical properties, the treated Nomex has a tensile elongation value increased by 30% compared to Kapton, at an operating temperature of 200 ° C. This function allows the correct control of the transfer of energy from the moving coil to the dome in real working conditions.

In addition, this patented material is also suitable for use in environments with a high moisture content. Finally, the powerful ferrite magnet was designed to obtain 16,000 Gauss of magnetic flux inside the air gap, even though it is a compact motor.
