Epoque Aeon Wall

The Flagship product Epoque Aeon Wall sets the
Ultimate benchmark for High Efficiency Loudspeakers.

The core of our Epoque Aeon Wall is represented by the “Carbon Excellence Aeon“ bending wave driver that is based on the patented bending wave technology by Göbel®. This “Carbon Excellence Aeon“ bending wave driver inspired by the principals of sound creation through musical instruments and is the result of over 15 years of development we invested in order to achieve the most natural sound possible.

In order to achieve an absolute homogeneous sound dispersion and stimulation of the room modes within the low frequency range, the Epoque Wall is additionally equipped with 6 custom built Göbel® Aeon 7 inch long throw aluminum bass drivers. These symmetrically arranged bass drivers are specifically located on the front to create an absolute smooth transition from the „Carbon Excellence“ Aeon bending wave driver`s broad frequency range to the low frequencies of the custom built bass drivers.

The purely functional design with the perfectly defined form and the use of specific aluminum alloys in combination with our special high density, bulletproof, multilayered composite materials, eliminate any diffractions, resonances and energy saving effects.

FEATURED TECHNOLOGIES

Carbon Excellence Bending Wave Driver Front Dispersion
The world wide unique Göbel Carbon Excellence Aeon bending wave driver covers the enormous bandwidth from 170 Hz to 31.000 Hz with a constant frontside dispersion of nearly 180 degrees. Through this, the Epoque Aeon Wall is a maximally coherent speaker that completely avoids time and phase problems from the outset. The phase velocity is always faster on the membrane than it is in air, resulting in an unbelievably fast sound with a tremendous resolution without any indication of efforts – even at high volumes. In addition to that, the almost non existing mass of the GÖBEL bending wave membrane completely avoids problems caused by mass inertia such as impulse deadening which always occurs in conventional loudspeaker systems.

Carbon Excellence Bending Wave Driver Rear Dispersion
In the Epoque Aeon Wall the patented Göbel Carbon Excellence Aeon bending wave driver also has a rear-side dispersion through the air pressure ventilation slots. Herefore, the backside of the Göbel Carbon Excellence Aeon bending wave driver has a hyperbolic construction where the rear-side dispersion is guided and also damped by a sort of flow resistance. This avoids any comb filter effects through the back wall from the outset, which otherwise would be caused by reflections within this most important frequency range. You will experience this in a detached and uncolored sound reproduction without any resonances.

Lossless Bass Drivers
In order to get a perfectly smooth transition from the patented Göbel Carbon Excellence Aeon bending wave driver to the low frequency drivers, we had to develop incredibly fast and absolutely linear bass drivers for the Epoque series. The motor systems are optimized to the maximum linearization of the magnet field in both directions of the extremely high excursion area resulting in the lowest and smoothest possible harmonic distortion spectrum. Furthermore, all materials we use here are of unparalleled quality, making it possible to reach the minimum possible loss factors and the fastest impulse behavior. Only to sum a few: Glasfiber voice coils, extremely lossless spiders and gaskets, extensive ventilation, extremely rigid aluminum membranes, etc.

Multiple Bass Array
To get an even more accurate and fast bass response, we use multiple arrays of bass drivers. These special bass drivers are mounted in a particular array on the front-side of the enclosure in order to activate the room modes completely uniformly. Of course we also adjusted the outstanding dispersion behavior of the Carbon Excellence Aeon bending wave driver to the low frequencies. In terms of maximum sound pressure level, a lot of air has to be moved when the frequency drops. Therefore the surface area sum of the bass drivers for a pair of Epoque Aeon Wall is greater than the surface area of 2 pcs 12 inch woofers but with much more coherency and speed.

Ultra Rigid Sandwich Enclosure
The enclosure of the Epoque Aeon Wall is an absolute non-compromise design, where all our knowledge about material resonances was applied. Based on our bending wave technology, we certainly know exactly how to manage surface waves on enclosure materials so they don’t even start to arise. For the Epoque Aeon Wall we use our proprietary multilayered composite material in combination with a special aluminum alloy in order to prevent any resonances in the working areas of each driver. Through this ultra rigid combination of materials we also avoid any energy saving effects. This results in an unbelievably uncolored sound reproduction with tremendous attack and speed in front of an absolutely silent background.

Totally Isolated Crossover
The meticulously selected crossover network parts are housed in two totally sealed cabins inside of the loudspeaker enclosure. These cabins are located in the top and in the bottom of the enclosure in order to protect them against air pressure differences and resonance patterns, which always occur in loudspeaker enclosures. Additionally, the crossover-path for the bending wave loudspeaker and the crossover-path for the bass drivers are located in completely separated chambers to avoid any crosstalks, electro-magnetic couplings, or any other interferences between them. Furthermore, each network component is hand wired point-to-point to avoid parasitic effects of pc-board type constructions. Finally, all crossover parts are moulded with a special damping epoxy to avoid any microphonic effects. All of these efforts lead to an unbelievably natural sound reproduction which is hard to imagine if you have not heard it.

Flat And Tiltable Wall Mount
The Epoque Aeon Wall comes with a special proprietary massive steel wall mount, which is also tiltable in order to adjust the loudspeaker perfectly to the listening position. After adjusting these angles, the Epoque Aeon Wall can be fixed with screws within this wall mount. In order to not lose any space, everything is designed to keep the overall depth of the mounted Epoque Aeon Wall as small as possible.
