Estelon was founded in Tallinn, Estonia in 2010 by Alfred Vassilkov, a loudspeaker designer with decades of experience who wanted to build speakers that were simultaneously world-class acoustically and genuinely beautiful as objects in a room. The result is a range of loudspeakers whose curved, marble-based cabinets are unlike anything else in high-end audio — not as a stylistic statement, but because the curved, resonance-free enclosure is the engineering solution that Vassilkov believed produced the best sound. Every Estelon speaker is built by hand in Tallinn by a small team of craftspeople who treat each pair as a commission, not a production run. ENGINEERING PHILOSOPHY The fundamental engineering insight behind every Estelon design is that a loudspeaker cabinet should be acoustically inert and mechanically stable — and that achieving this with conventional materials and rectangular shapes requires compromises that ultimately colour the sound. Estelon's curved enclosures, constructed from a proprietary composite material with a marble base, eliminate internal standing waves and provide a mechanical grounding that allows the drivers — sourced from the finest European manufacturers — to operate with complete freedom. The crossover networks are point-to-point wired, using components chosen for their sonic character rather than their specification alone. What you hear from an Estelon speaker is not the cabinet. It is the music. WHY THE AUDIO TAILOR CARRIES ESTELON We carry Estelon because it answers a question that matters to a growing number of our clients: why should a world-class loudspeaker have to be hidden away or apologised for aesthetically? An Estelon speaker belongs in a beautiful room. It is also, by any measure, among the finest speakers in the world. Estelon AURUS Powerful Low Frequencies. Effortless Depth. The Estelon AURUS subwoofer extends the low-frequency performance of any high-end audio system with deep, controlled bass and refined dynamic impact. Designed to integrate seamlessly with Estelon’s A Series loudspeakers, AURUS delivers an immersive foundation that enhances scale, realism, and emotional engagement without drawing attention to itself. With advanced driver technology, a 1200 W amplifier, and sculptural design, the AURUS combines authoritative bass performance with elegant visual presence—adding both sonic depth and aesthetic sophistication to any space. Design Philosophy: Bass That Belongs to the Room At Estelon, subwoofers are designed to work in harmony with their acoustic environment. Every surface in a room influences how low frequencies are perceived, which is why the AURUS is engineered to integrate naturally rather than dominate the space. The goal is for the subwoofer to disappear sonically—leaving only powerful, controlled, and emotionally engaging bass that feels fully connected to the main loudspeakers and the music itself. Advanced Cabinet Technology The Estelon AURUS cabinet combines precision-milled plywood with a thermoformed, mineral-doped composite shell, creating an exceptionally rigid and acoustically inert enclosure. Multi-material construction suppresses resonance and vibration Adhesive bonding further enhances damping and structural stability Sculptural outer shell complements modern interiors This advanced cabinet design houses a 346 mm long-excursion driver working in conjunction with a passive radiator. The passive radiator increases low-frequency extension and output while eliminating port noise, resulting in clean, distortion-free bass reproduction with excellent transient control. Driver & Amplification System At the heart of the AURUS is a powerful, precisely controlled amplification stage: 1200 W bridged Class-D amplifier High current capability for tight, accurate bass even at high output levels Designed for low distortion, speed, and long-term reliability This combination ensures effortless low-frequency performance that remains composed, articulate, and musically expressive under all listening conditions. Filter & Input Configuration The AURUS subwoofer features a flexible and highly refined signal-processing system for seamless system integration. Dual Input Options Active analogue line-level input (XLR) with built-in filtering Passive high-level input for speaker-level connection Speaker-Matched Filter Profiles Four selectable filter profiles are provided, specifically optimised for AURA and AURELLE loudspeakers. These are easily selected via rear-panel switches. Level & Phase Precision Level adjustment of ±6 dB for active input 0 or +3 dB gain options for passive input Ultra-low latency filters ensure precise phase alignment with the main speakers This system guarantees seamless blending, accurate timing, and coherent bass integration across the entire frequency range.
