Stenheim, the Switzerland-based speaker company that utilizes aluminium cabinets and high-efficiency drivers to bring out every nuance of the finest recordings, will unveil its new active subwoofer at High End Munich.

The new Alumine Sub has been principally designed to complement the speaker models in Stenheim’s own Alumine range, although its development has ensured it works equally advantageously with speakers from other brands. Existing and potential owners of Stenheim’s smaller Alumine models, the Two and the Two.Five, will benefit from notably extended bass in their system with the addition of the new subwoofer, which will prove particularly effective in larger room applications.
While naturally adding lower bass response to any partnering speaker, one of the Alumine Sub’s greatest strengths is in its ability to articulate remarkable bass dynamics and texture, critical factors to a life-like listening experience. Sophisticated on-board digital signal processing, which allows precise control over frequency, gain and phase, enables the new subwoofer’s sound to be tailored to match an individual room’s characteristics. This presents obvious advantages to owners of Stenheim’s larger Alumine models, the Three and the Five too, allowing them to enjoy an enhanced bass performance as well as the ability to dial in their in-room sound.
The new Sub is an active design featuring audiophile electronics that include a powerful 1200 W amplifier. Its multiple parameters are controlled remotely via either an app installed on a smartphone or tablet, or via a dedicated web page. Multiple connection possibilities enable it to be integrated easily into a wide variety of audio systems as well as making it eminently suitable for high quality home cinema installations.
The Alumine Sub adheres to Stenheim’s acclaimed design philosophy with an all-aluminium construction and ingenious internal chambering, which contains three distinct volumes. It also continues Stenheim’s track record of achieving truly surprising performance from comparatively modest external dimensions. This is thanks in no small part to the Sub’s clever isobaric design, which maintains a constant pressure between the two drivers to lower distortion levels and minimize the overall size. The acoustic alignment design also ensures superior dynamics throughout the frequency range, giving fast attack and response, characteristics that typify the Stenheim sound and breathe life into the music.
The Alumine Sub will be shown at Munich High-End in the Stenheim room, Atrium 4.2 F213, and is already available to order.
About Stenheim
Stenheim is part of a long and vibrant tradition of Swiss audio excellence and is a deserved member of the pantheon of famous Swiss hi-end brands. At the heart of the Stenheim design philosophy is a belief in the use of solid aluminium for totally inert cabinet enclosures that eliminate coloration, enabling the micro detail of the music to be heard. This, allied to high-efficiency drivers maximising speed and dynamics, produces an intensely musical result that renders every nuance of the musician’s expression.
