Morel Ultimo PowerSlim PS104D: 10-Inch SQ Shallow-Mount Subwoofer

The Morel Ultimo PowerSlim PS104D delivers the reference-level sound quality of the legendary Ultimo series in a revolutionary shallow-mount design. Engineered for music lovers who refuse to compromise on audio fidelity but face space constraints, this 10-inch subwoofer provides deep, accurate, and musical bass from enclosures as small as 14.2 litres (0.5 cu ft). It is the ultimate solution for achieving high-end bass performance in sports cars, utes, and any vehicle where space is at a premium.

At the heart of the PS104D is Morel’s commitment to innovation. It incorporates the brand’s most advanced technologies, including the massive EVC™ (External Voice Coil) with a Hexatech™ aluminium coil, a Uniflow™ die-cast chassis, and a Progressive Field Symmetry (PFS) motor structure. These elements work in harmony to produce a subwoofer that is powerful, linear, and incredibly articulate, faithfully reproducing the nuances of your music without distortion.

Key Features:

• Reference Sound Quality: Experience the deep, tight, and musical bass characteristic of the flagship Morel Ultimo series.
• Ultra-Shallow Design: With a mounting depth of only 84mm (3.3 inches), it allows for flexible installation in the tightest of spaces.
• High Power Handling: Conservatively rated at 600 Watts RMS for reliable, high-output performance.
• Advanced Motor Structure: Features Morel’s PFS™ (Progressive Field Symmetry) technology for maximum linearity and minimal distortion.
• Signature EVC™ Technology: Utilises a huge 4-inch Hexatech™ aluminium voice coil for exceptional power handling and thermal efficiency.
• Built for Small Enclosures: Optimised for use in compact sealed enclosures, delivering precise and controlled bass response.

Technology Breakdown

• PFS (Progressive Field Symmetry) Motor: The optimised magnetic motor generates a symmetrical magnetic field, ensuring the voice coil remains within a linear field during its excursion. This dramatically reduces distortion, particularly at high power levels, and improves overall driver control.
• EVC™ (External Voice Coil) & Hexatech™ Coil: Morel’s signature EVC architecture places the motor magnets inside a large 4-inch voice coil. This design improves cooling, increases power handling, and reduces cone breakup for a cleaner sound. The Hexatech™ aluminium wire, shaped like a honeycomb, is 100% efficient in its winding, further enhancing durability and efficiency.
• Uniflow™ Aluminium Chassis: The cast aluminium basket is designed to be aerodynamically efficient, minimising air pressure buildup beneath the spider. This reduces distortion and resonance, allowing the subwoofer to perform quietly and accurately.
• Hybrid Paper-Carbon Fibre Cone: The composite cone provides the ideal combination of stiffness, low mass, and excellent damping. This results in a fast, responsive, and natural-sounding bass reproduction.
