About the Alumine Five
The Alumine Five is a Swiss-made, passive 3-way floor-standing speaker featuring a full aluminium cabinet with four independent chambers and a front laminar port bass reflex design. It uses 2x 25cm (10") woofers, 1x 15-16.5cm (6.5") midrange driver, and a 2.6cm (1") soft dome tweeter, all custom-built to Stenheim's specifications for speed, tonality, and musicality. The crossover is phase coherent and employs high-grade audiophile components from boutique suppliers such as Mundorf and Jantzen, ensuring optimal driver integration and minimal signal loss. The speaker has a frequency response of 28Hz to 35kHz, sensitivity of 94dB SPL, nominal impedance of 8 Ohms (minimum 3 Ohms), and power handling of 200W RMS (400W peak). Dimensions are approximately 28cm wide x 38cm deep x 120cm high (without platform), and weight is about 100kg per speaker. In 2024, Stenheim introduced the Alumine Five Platform, a solid billet aluminium plinth with adjustable spikes for improved stability, vibration damping, and setup fine-tuning, which can be retrofitted to existing models. Variants include the Alumine Five SE (Special Edition) with enhanced crossover and wiring, Alumine Five SX with the new platform and upgraded components, and the limited Alumine Five LE featuring luxury finishes and gold leaf details. The Alumine Five is noted for its high efficiency allowing pairing with low-powered amplifiers, and its design philosophy emphasizes musical fidelity and timeless build quality.
