Stenheim makes a refined entry into the ultra high-end subwoofer market with the debut of the Alumine Sub at High End Munich 2025. Unlike the heavy-hitting competitors aiming to dominate the low end with sheer power, the Alumine Sub focuses on delivering bass with unparalleled finesse and control. Designed as an active 10-inch subwoofer, it seamlessly integrates with Stenheim’s Alumine loudspeakers, particularly the Two and Two.Five models, while also maintaining compatibility with other brands.
Engineered with precision, the Alumine Sub boasts a full aluminum construction featuring an intricate three-chamber internal structure and an isobaric topology. This design ensures constant pressure between the two 10-inch high-excursion drivers, effectively reducing distortion and allowing for a compact yet powerful enclosure. The 1200-watt audiophile-grade amplifier provides robust performance, articulating low-end textures and dynamic nuances with startling realism that elevates any high-fidelity system.
