Gobel High End Epoque Aeon Baforce

The flagship product Epoque Aeon Baforce sets the ultimate benchmark for subwoofers.

The Epoque Aeon Baforce subwoofer is the choice for the ultimate sub-bass reproduction. In order to achieve an absolute homogeneous sound dispersion and stimulation of the room modes within the sub-bass frequency range, the subwoofer Epoque Aeon Baforce is furnished with 16 custom built Göbel® Aeon 9 inch long throw aluminum bass drivers which are arranged in a specific array.

These symmetrically arranged bass drivers are located on the left and right side of the enclosure and are impulse compensated. Due to this particular impulse compensated array of the bass drivers and the fact that each of these custom built bass drivers is mounted in its own sealed chamber, an ideal impulse behavior, the best possible control and therefore the fastest possible bass response is guaranteed.

The Epoque Aeon Baforce series is available as an active or passive version, so the customers also have the choice using their preferred amplification.

In the active version, each bass driver has it’s own 250 Watt amplifier, so 16 x 250 Watt generate full 4000 Watt. The massively oversized power supply can shortly deliver 4 times higher peak current as the amplifiers will need at maximum level. This is permanently controlled by a micro controller in order to always have secured conditions. All of this is mounted in the loudspeaker foot, which is milled out of a full block of a specific aluminum alloy in order get the perfect control over EMI, crosstalk, heat dispersion and resonance patterns.

The crossover / controller of the Epoque Aeon Baforce is always excluded and is available under the name “Epoque Aeon Baforce Controller”. We deliberately outsourced the totally analog high end active crossover / controller in an external enclosure, so the small signals are not influenced by the massive current / voltage of the amp / power section, as well as by their mechanical resonances and huge magnetic fields.

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 from the outset.

Reviewer Statements

The Göbel Epoque with its unique bending wave driver covering a frequency range from 180 Hz to 31.000 Hz sounded detailed and extraordinary coherent.»

Featured Technologies

In order to get an ideal impulse behavior and therefore the fastest possible bass response, we had to develop incredibly fast and absolutely linear bass drivers for the Epoque Aeon Baforce. The motor system is 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.

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 left and the right side of the enclosure in order to activate the room modes completely uniformly. Additionally, each of these custom built bass drivers is mounted in their own sealed chamber in order to get the best possible impulse behavior and therefore the fastest possible bass response with maximum control. 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 all bass drivers in one Epoque Aeon Baforce is greater than 3,600 cm2! And all this with a linear excursion of more than 2 cm!

Impulse Compensation

Our ultra lossless bass drivers are mounted impulse compensated in the enclosure of the Epoque Aeon Baforce. Through this additional technology and based on the usage of our proprietary ultra rigid sandwich enclosure materials, the already ultra low harmonic distortions and material resonances are once again reduced to nearly one tenth part. You will experience this in an even higher resolution, effortlessness and even quicker transient response in the bass and sub-bass area.

Ultra rigid Sandwich Enclosure

The enclosure of the Epoque Aeon Baforce 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 Baforce, we only 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.

Direct coupled bass drivers to the amplifiers

Each bass driver in the active version of our Epoque Aeon Baforce has it’s own 250 Watt/sin. amplifier and is directly coupled to it’s output. For the active version of our Epoque Aeon Baforce subwoofer we are using 16 amplifiers, each delivering 250 Watt/sin. = 4 KW/sin. in total! The power amplifiers are specially adapted Class H types with a very low output impedance. Through this, we reach a stunningly high damping factor and get the best possible control over each bass driver. Additionally, we hereby also avoid influences through back EMI from the outset. All of this results in a bass reproduction with the best possible impulse behavior and maximum control, that you have never experienced before.

Massively Oversized Power Supply

The massively oversized high end power supply can shortly deliver 4 times higher peak current as all the amplifiers need at maximum level. This is permanently controlled by a micro controller in order to always have secured conditions. To lower the interferences even more, we designed the enclosure so the power supply has it’s own shielded chamber and doesn’t affect the analog section. Hereby every dynamic impulse is reproduced with unbelievable velocity and precision so every small dynamic detail of music is unveiled without compression.

Totally EMI and Resonance Proof Enclosure

All of the electronic units are housed in a non-compromise enclosure which is milled out of a full block of a specific aluminum alloy. Hereby we get perfect control over many important aspects like avoiding EMI, the ideal heat dispersion, the freedom from magnetic interfering fields, an ideal resonance behavior of the complete system, etc. In order to lower the interferences even more, we designed the enclosure so every unit has it’s own shielded chamber and components like the power supply and micro controller don’t affect the analog section.
