Stenheim has recently unveiled a new addition to their esteemed Alumine line of acoustic products, introducing the Alumine Two.Five, a floor-standing speaker system that stands as an exciting development for audiophiles. This new model serves as a perfect intermediary between the Alumine Two bookshelf speakers and the Alumine Three floorstanding speakers, enriching the series with its innovative design.

The Alumine Two.Five boasts a comprehensive redesign that elevates sound performance to new heights. It incorporates a blend of foundational elements that have consistently defined the Alumine series. Among these are its aluminum enclosures, high-efficiency drivers, and a unique crossover design that has been a hallmark of the series. For instance, the Alumine Two’s remarkable sound distinction is achieved through a crossover that connects with just two speakers—a tweeter and a woofer.

The engineers at Stenheim have adapted this principle for the Alumine Two.Five, enhancing the internal space and extending the bass response. Despite the complexity, the crossover maintains its dual-sided configuration to ensure reliability. Unlike its predecessors, the Alumine Two.Five utilizes not just one, but two 6.5-inch woofers, paired with a one-inch tweeter, promising an unparalleled audio experience.


The developers have designed the Alumine Two.Five floorstanding speakers to be highly versatile, ensuring compatibility with nearly any power amplifier. This adaptability allows them to deliver high-quality sound even when paired with less powerful systems, making them a flexible choice for a wide range of audio setups.

Crafted by hand in Switzerland, these speakers embody a synthesis of meticulous craftsmanship and aesthetic design. Their classic and elegant appearance allows them to seamlessly integrate into any interior decor, enhancing the visual and auditory ambiance of the space.

Performance-wise, the Alumine Two.Five speakers operate across a broad frequency range of 35 Hz to 30,000 Hz. They boast a sensitivity of 93 dB and an impedance of 8 ohms, ensuring efficient and dynamic sound reproduction. With a power consumption of 125 W (peaking at 250 W) and a minimum recommended power of just 10 W, these speakers combine efficiency with power. Each speaker measures 94.5 cm in height, 23 cm in width, and 27.5 cm in depth, and weighs 45 kg, indicating a solid and substantial build quality that contributes to their superior sound performance.
