Choice of materials and craftsmanship - the basis for uncompromising sound
Before the horn of The-Final could take shape, one key question arose: Which material would meet the highest acoustic requirements while simultaneously enabling the complex horn contour? After extensive testing, the choice fell on high-quality acrylic - a valuable material with excellent internal damping, ideal workability, and the ability to precisely realize the special shape. Acrylic can, of course, be supplied in your desired color.

 

Acrylic: Acoustically superior, visually flawless
The horn mounting ring and the carrier ring for the Fullrange Chassis are milled from solid white acrylic sheets and then hand-polished to a high gloss. Acrylic not only provides stability and precision, but also avoids disruptive magnetic interactions that can occur with metals. The rear edges of the carrier ring are rounded to prevent disruptive edge diffraction, while a wafer-thin Sorbothane damping layer decouples the Fullrange Chassis from the horn - for maximum clarity and detail.

 

Precision through high-tech and simulation
The implementation of this complex concept was made possible through collaboration with the experienced mechanical engineer and patent holder Andreas Wehrle. He created detailed 3D models of all components, conducted extensive vibration analyses, and developed programs for CNC manufacturing. The goal was to perfectly tune the horn and all assembly parts to eliminate resonances - so that only the pure movement of the diaphragm remains audible.

 

The horn carrier - Stability meets elegance
The horn carrier not only has to support the five-kilogram horn, but also prevent any unwanted vibration. Due to the bending radii and the load, steel tubing was chosen. However, steel has very low internal damping - so Dr. Oehlrich and Mr. Wehrle simulated countless variations on the 3D model. Only a special filling of the frame achieved the desired resonance-free state and suppressed any sound-damaging vibration.

 

Top-quality craftsmanship "Made in Germany"
Despite all the high-tech machining, craftsmanship remains the decisive factor. The acrylic surfaces are polished to a high gloss, the axes of the retaining ring are welded by hand, and the horn carrier is precisely reworked after bending. Several layers of copper are electroplated and polished again until the surface is flawless. The finishing touch is a sophisticated chrome or hard gold coating - brilliant appearance and maximum durability in one.

 

Attention to detail
A special highlight is the polished, threadless adjusting screw for precise tilt adjustment of the horn - a small masterpiece that perfectly combines technology and design. The result is a speaker that combines state-of-the-art manufacturing and genuine craftsmanship, combining audiophile performance with a sculptural appearance.
