Morel Ultimo PowerSlim – PS 104D

The Morel Ultimo 104D PowerSlim is a shallow-mount subwoofer engineered to redefine what’s possible in bass reproduction—combining compact dimensions with unmatched output, precision, and durability. Honored with the EISA “Best In-Car Subwoofer” award for 2023–2024, it stands as a testament to Morel’s relentless commitment to innovation and exceptional sound quality.

Drawing inspiration from the acclaimed Ultimo Titanium, the PowerSlim is purpose-built for environments where installation depth is limited but performance expectations remain high. At its core lies Morel’s advanced EVC™ (External Voice Coil) motor technology with a massive 5.1-inch voice coil—the largest in its class. Crafted from lightweight Hexatech™ aluminum wire, this design delivers unmatched power handling, superb linearity, and exceptional control, ensuring rich, accurate, and dynamic bass response.

The Ultimo PowerSlim’s ultra-slim profile—just 3.1” (78mm) for the 10-inch and 3.4” (86mm) for the 12-inch models—is made possible by its Uniflow die-cast aluminum chassis, Progressive Field Symmetry (PFS) suspension, and HexaCore carbon fiber–aluminum honeycomb flat piston cone. Together, these components enable impressive excursion and high output from the most compact enclosures.

With its uncompromising engineering, the Ultimo 104D PowerSlim delivers the full, powerful, and detailed bass you expect—using nearly half the space of conventional subwoofers.
