Swiss Precision Meets Bass Authority: The Stenheim Alumine Sub

Swiss audio manufacturer Stenheim has unveiled its remarkable new subwoofer, the Alumine Sub, designed to seamlessly complement any two-channel system with profound low-frequency extension. This audiophile-grade subwoofer showcases Stenheim's signature all-aluminum construction, features dual 10-inch high-excursion drivers, and incorporates a powerful 1,200-watt amplification module. The multiple parameters are controlled remotely via either an app installed on a smartphone or tablet, or via a dedicated web page, offering unprecedented flexibility for various acoustic environments.

Engineered for Musical Synergy

The Stenheim Alumine Sub was primarily conceived as the perfect companion to Stenheim's acclaimed Alumine series loudspeakers, while maintaining exceptional compatibility with other high-quality speaker brands. Current owners of the Stenheim Alumine 2 and Alumine 2.5 will find this subwoofer transforms their systems with significantly enhanced and better-extended bass response, particularly beneficial in larger listening spaces. Beyond merely adding low-frequency content, Stenheim claims that the Alumine Sub also delivers "remarkable bass dynamics and texture," which it describes as essential to creating a realistic listening experience.

Thanks to sophisticated onboard digital signal processing, the bass performance can be precisely tailored to individual room characteristics, enabling accurate control over frequency response, gain, and phase parameters. The new subwoofer extends its benefits to owners of Stenheim's flagship models—the Alumine 3 and 5—allowing them to experience enhanced low-frequency performance and the opportunity to fine-tune their acoustic experience, especially in larger rooms.

Swiss Engineering Excellence

The Alumine Sub embodies Stenheim's celebrated design philosophy through its all-aluminum construction and ingenious internal chamber architecture, incorporating three distinct acoustic spaces within its compact footprint. This continues Stenheim's tradition of achieving truly astonishing performance within remarkably compact dimensions. Much of this achievement stems from the Alumine Sub's clever isobaric design, which maintains constant pressure between the two driver units, significantly reducing distortion levels while minimizing overall cabinet size.

The acoustically symmetrical design ensures superior dynamic performance across the entire frequency spectrum, delivering the rapid transient response and impact that define Stenheim's musical signature—breathing life into every musical passage.

Active Design with Audiophile Refinement

This sophisticated subwoofer employs an active design featuring audiophile-grade electronic components and a robust 1,200-watt amplification circuit. Its comprehensive parameter set can be managed through smartphone or tablet applications, or via a dedicated web interface, ensuring compatibility with future software updates and evolving technology standards.

Multiple connectivity options enable effortless integration with diverse audio systems, making it exceptionally well-suited for high-quality home theater applications. The Alumine Sub is available in standard light gray or dark gray finishes with black front and rear panels. Custom color options include full black, ivory white, or mocha finishes, all featuring black panels to harmonize with any existing Stenheim or other premium speaker systems.
