Stunning Finish Options

Design Philosophy: Sound Shaped by Space
Estelon understands that true fidelity emerges from a harmonious relationship between speaker and room. The low frequencies are optimally positioned close to the floor for balanced bass distribution, while mid and high drivers are vertically aligned to minimise reflections, resulting in a natural, immersive soundstage that adapts to your listening environment.
Advanced Cabinet Technology
Crafted from a proprietary marble-based composite, the cabinet features flowing curves with no flat panels, eliminating internal resonances. Each driver resides in its own optimised chamber, ensuring tonal neutrality and ultra-low distortion across the 23 Hz to 60 kHz frequency range.
Precision Driver System by Accuton
• 280 mm ceramic sandwich woofer for deep, controlled bass response • 173 mm ceramic mid-woofer delivering articulate midrange clarity • 25 mm diamond membrane tweeter offering unmatched resolution and extension
Every driver is time-aligned on a curved baffle, expanding the sweet spot and preserving phase coherence for exceptional spatial realism.
Custom Connector Innovation
Estelon’s piano-key-inspired, spring-loaded binding posts ensure consistent contact pressure and pure signal transmission. Copper foil ribbon conductors eliminate multiple contact points, reducing colouration and maximising transparency.
Precision Crossover Design
Housed in an isolated chamber and built with Mundorf and Jantzen capacitors, Goertz inductors, and Kubala-Sosna point-to-point wiring, the second-order crossover at 86 Hz and 2 kHz seamlessly blends each driver, delivering pristine timbral accuracy.

Audiophiles and discerning listeners seeking both show-stopping aesthetics and uncompromising performance will appreciate the Signature MK2’s blend of craftsmanship and technology.
