Ultimo Pro

The Legacy of Precision and Musicality in Bass

The Ultimo Pro continues the legacy of Morel’s renowned Ultimo subwoofers, setting a new standard for car audio bass reproduction. Designed for audiophiles seeking pure sound quality, the Ultimo Pro delivers controlled, musical bass with extraordinary output and minimal distortion, making it the ultimate choice for those who demand excellence.
At the core of the Ultimo Pro lies a massive 5.1″ Hexatech™ aluminum voice coil, one of the largest ever designed for car audio. This advanced coil is engineered not only for remarkable heat dissipation but also for creating a piston-like, linear motion. By improving the control over the diaphragm’s movement, the 5.1″ coil minimizes distortion, allowing for a clean, natural bass response. This precision ensures that every note is delivered with both power and clarity, faithfully reproducing the original recording.

Morel’s unique hybrid carbon fiber and paper one-piece cone further enhances the Ultimo Pro’s performance. Combining the lightweight stiffness of carbon fiber with the natural damping properties of paper, the cone offers remarkable strength and precision while minimizing unwanted resonances.  The seamless, one-piece construction provides uniform movement, ensuring optimal bass performance with minimal distortion.
The Ultimo Pro’s newly engineered double suspension system enhances its linearity and precision, providing superior excursion and responsiveness. Designed for use in both sealed and ported enclosures, the Ultimo Pro offers powerful, accurate bass with tight control—ensuring that low frequencies are reproduced with exceptional detail and musicality.
The Ultimo Pro is the culmination of Morel’s decades of experience, combining cutting-edge technology, innovative design, and superior craftsmanship. It’s not just a subwoofer—it’s the next evolution in bass reproduction, continuing the legacy of the Ultimo series and setting the benchmark for performance in car audio.
