Specifikation och beskrivning:

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.

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.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.
