ESB Car Audio 9.3M Series 9000 high-end 3"/75 mm midrange

The Midrange 9.3M from ESB Car Audio's Series 9000 is another milestone in the evolution of high-end car audio. Designed for the most demanding audiophiles, this speaker offers a perfect combination of advanced technology and high-quality materials. The heart of this midrange is the magnet pole yoke, optimized through sophisticated magnetic flux analysis software.

This design ensures uniform saturation of the magnetic gap, improving coil travel and reducing distortion, offering superior audio dynamics. The generously-sized neodymium magnet is resistant to high temperatures, offering excellent performance in a compact format. The TCA (Air Flow Control) system manages the air flow generated by the cone, ensuring controlled and efficient release of energy accumulated in the speaker's movement, for precise and faithful reproduction of the audio source.

The light and wide moving coil, made of Nomex with aluminum winding, contributes significantly to bandwidth extension, providing detailed and dynamic sound. The balanced Conex™ spider surround ensures linear movement in both directions, reducing distortion and guaranteeing accurate audio reproduction. The die-cast aluminum basket with powder coating offers low air resistance, while the high-modulus carbon cone, vacuum-pressed and autoclaved, offers natural and dynamic reproduction.

The NBL rubber surround, designed for fluid movement at very low excursion, contributes to the speaker's dynamicity and its ability to handle high power. Optionally, a CNC-machined aluminum grille is available, which adds a touch of elegance and protection to the speaker.
