The Morel Ultimo 104D is a 10-inch high-end subwoofer featuring dual 4-ohm voice coils, designed to deliver audiophile-grade bass with precision, depth, and musicality. As part of Morel's flagship Ultimo series, the 104D offers the same meticulous engineering as its larger siblings, in a compact form factor ideal for sealed enclosures and space-limited installations.
🛠️ Compact Size, Massive Performance
Despite its 10” diameter, the Ultimo 104D houses a 5.1” (130mm) Hexatech™ aluminum voice coil – one of the largest ever built into a 10-inch subwoofer. Coupled with a double-stacked ferrite magnet and vented pole structure, it ensures exceptional thermal handling, control, and linear excursion for deep and accurate bass reproduction.
