Design Philosophy
At Estelon, we believe that a loudspeaker must work in harmony with the space it inhabits.
Every surface in a listening room influences how music is heard.
Our goal is to design loudspeakers that interact naturally with their environment, creating a lifelike and emotionally rich experience.
At low frequencies, sound behaves like atmospheric pressure rather than directional waves.
This is why we position the woofer near the floor, allowing it to couple with the surface and distribute bass evenly.
At frequencies above 100 Hz, sound becomes more directional and susceptible to reflections.
We group the mid-woofer and tweeter together and position them higher on the cabinet for coherence and a stable stereo image.
In all Estelon designs, the midrange driver is placed above the tweeter to further improve upper bass and low midrange accuracy.
Cabinet Technology
The XB Diamond Mk II cabinet is crafted from Estelon’s proprietary marble-based composite material using advanced moulding technology.
It features no parallel walls and an internal system of curved surfaces and chambers.
Each driver sits in an acoustically optimised enclosure tailored to its function.
Internal bracing and carefully positioned dampening materials minimise unwanted resonances, supporting the drivers without adding coloration.
Driver System
-
- The XB Diamond Mk II features three drivers, custom-designed with Accuton:
- 220 mm ceramic sandwich woofer – deep, accurate bass
- 158 mm ceramic mid-woofer – clean, extended midrange
- 25 mm diamond membrane tweeter – extraordinary detail and spatial precision
- The woofer is placed in a bass reflex chamber with a rear port.
- The tweeter is housed in its own isolated enclosure with a curved face for even dispersion.
- The XB Diamond Mk II features three drivers, custom-designed with Accuton:
Driver Positioning and Dispersion Control
All drivers are positioned on a curved front panel to ensure they are equidistant from the listener.
The cabinet’s soft curves reduce diffraction, expanding the sweet spot and ensuring consistent tonal balance across a wide listening area.
Crossover Design
The XB Diamond Mk II uses precision crossover filters housed in their own dedicated chamber, protecting them from vibration.
Crossover points:
- 90 Hz and 2.2 kHz
- Third-order slopes between woofer and mid-woofer
- Second-order slopes between mid-woofer and tweeter
Hand-built crossovers feature point-to-point wiring using premium-grade solder.
Components include Mundorf and Jantzen capacitors, Goertz and Mundorf inductors, and Kubala-Sosna internal cabling.
