Estelon YB MKII - Black Gloss

Timeless design, powerful performance

The Estelon YB Mk II blends striking design with immersive, life-like sound. Featuring an asymmetric Y-shaped cabinet, it brings both aesthetic elegance and acoustic precision into contemporary interiors.

 Incorporating advanced technologies and the latest upgrades, the YB Mk II delivers a pure, emotionally engaging performance in any room.

 

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.

 

Cabinet Technology

The YB Mk II uses a sealed-box cabinet concept, which is compact and less demanding in placement than bass reflex designs. The cabinet is formed using Estelon’s proprietary marble-based composite, shaped through

advanced moulding techniques into a rigid and acoustically inert structure.

 

Driver Configuration and Placement

The YB Mk II uses a unique angled woofer design. Positioned facing inward toward the opposite speaker, this setup helps reduce midrange reflections from nearby walls in smaller rooms.

It also improves stereo image stability in the lower frequencies up to 220 Hz. In some difficult acoustic situations, reversing the left and right speaker placement can further optimise performance.

The tweeter is a 26 mm beryllium dome Illuminator model from Scan-Speak. It is extremely lightweight and rigid, producing low distortion, excellent sensitivity, and precise impulse response. Its breakup modes occur beyond

the range of human hearing.

The mid-woofer is a 148 mm sliced paper cone from Scan-Speak’s Revelator series. The cone is damped with proprietary glue between the slices, reducing distortion and creating smooth frequency response. This results in clean, realistic

midrange reproduction with minimal colouration.

The woofer is a 220 mm aluminium cone from SEAS. It offers excellent bass precision with a lightweight cone, long excursion, and a low-loss rubber surround that suppresses edge resonance.

Each driver is housed in its own chamber, shaped to eliminate internal resonances and reduce vibration. The tweeter and mid-woofer share an isolated upper chamber, while the woofer is positioned in a separate sealed enclosure.

These chambers are fully dampened and constructed for optimal performance.

 

Crossover Design

The crossover components are carefully chosen for synergy and precision.

These include custom transformer-core coils, oxygen-free copper air-core coils, SESGO capacitors, and Mundorf wire-wound Supreme resistors. All parts are measured and matched in pairs for consistency.

The crossover network is constructed using point-to-point wiring with high-grade solder, and all connections are kept short to preserve signal purity. Internal cabling is provided by Kubala-Sosna, known for exceptional transparency.

The crossover is located inside the woofer chamber to minimise vibration and microphonic effects. The filters use third-order slopes between the woofer and mid-woofer, and second-order between the mid-woofer and tweeter.

Crossover points are set at 80 Hz and 2 kHz.

Each crossover is tested thoroughly, both electrically and through critical listening sessions, to ensure it meets our standards before final assembly.

 

Custom Finishing

The YB Mk II cabinet is finished through a meticulous, multi-week process involving twelve layers of paint, wet sanding, and final hand polishing.

Gloss and matte options are available, along with custom colours upon request. Every finish is completed by skilled artisans.
