Design Philosophy

• At Estelon, we design loudspeakers that work with the room, not against it. Every element in a space influences the way music is heard. Our goal is to create synergy between the speaker and its surroundings to deliver a natural, emotionally engaging listening experience.
• Low frequencies behave like air pressure, making the woofer’s position near the floor ideal for even bass distribution.
• Above 100 Hz, the mid-woofers and tweeter are grouped higher in the cabinet, reducing reflections and stabilising the stereo image.

Cabinet Technology

• AURA features a sealed-box cabinet made from thermoformed mineral-filled composite. Its curved surfaces eliminate parallel walls, helping to reduce standing waves and internal resonances.
• Weighing 34 kg per piece, the cabinet is dynamically stable, allowing drivers to perform with clarity and precision.
• Natural and synthetic dampening materials are precisely placed for tonal balance across the frequency range.

Driver Configuration and Placement

AURA is a 3-way system with one woofer, two mid-woofers, and one tweeter.

• Woofer: 250 mm hard-pressed paper cone from FaitalPro, downward-firing, located in the base for even bass dispersion.
• Mid-woofers: 2 x 132 mm Egyptian Papyrus fibre from SB Acoustics Satori, known for low distortion and tonal realism.
• Tweeter: 25 mm textile dome from Scan-Speak Illuminator series, housed in an elliptical waveguide for smooth dispersion.

Each driver is installed in a sealed, dampened chamber optimised for its role.

Crossover Design

AURA’s crossover network uses second-order slopes at 75 Hz and 2.3 kHz.

Components include air-core and iron-core coils, Auricap and Jantzen capacitors, and Mundorf bifilar resistors.

The crossover is hand-assembled with point-to-point wiring, housed in the woofer chamber for isolation from vibrations. Internal cabling is by Kubala-Sosna.
