Epos ES14N

Epos ES14N Walnut

Restarting EPOS could only mean re-creating the most famous model, the ES-14.

This was a 2-way speaker in a fairly big cabinet and classic looking cabinet, to be used on a dedicated stand.

The design should be classic, not lifestyle, only doing things that help with the sound and as straight forward as possible.

Analysing the old construction was interesting.

It used a 7“ woofer with Polypropylene cone and an underhang coil with a huge magnet, but multiple layers of VC winding to make the whole coil heavy in order to get a sort of roll-off in the response curve of the woofer.

The size of the woofer was not following any standard – too big for a 6.5“, but too small for an 8“.

But it was a clever choice, because you could get more drive at lower frequencies more like an 8“ and a midband character closer to the 6.5“.

The Epos ES14N cabinet itself is using more or less the same volume of the original ES-14.

That’s not a big surprise, as the cabinet volume is the result of the driver configuration and the defined bandwidth of the speaker.

However, the shape of the cabinet is different.

The front baffle is tilted to the back in order to time align the woofer and the tweeter plus it can help with the standing wave mode between front and back.

As the design is a reflex system, a port is of course needed.

It’s located on the back of the cabinet and the whole shape of the port has been chosen to minimise air flow noise.

In order to compensate for the open tube resonance of the port, some openings were added in the middle of the port.

To avoid loss of low bottom end, those openings are covered with soft material, tuned to only kill the unwanted resonances of the port.

The cabinet uses a double layer MDF construction, glued together with the latest generation of damping glue.

This latest generation is more consistent compared to older solutions and allows easier production.

Additional bracing has been used to control the panel vibration modes and reduce the unwanted radiation of the whole cabinet. Only a little damping material is needed internally.

The front plate is an extra part to be glued and screwed on the main cabinet.

It has a 45° chamfer around it to control diffraction effect in the 2000-3000Hz region.

The first prototypes used square cabinets and it was impossible to get a good frequency response on axis and out of axis.

Rounding the corners was not really helping, only the chamfer made the diffraction error a lot smaller and helped balancing the upper midband.

An old fashion way, but a useful solution.

The speaker comes with front grille, but it is not recommended to use it when listening to music.

It’s more a protector when not using the speakers.

The tweeter itself is protected anyway and the PP cone is not easy to damage.

The alignment of the box is a flat 4th oder alignment with a tuning frequency of 38Hz.

It matches with the bottom end gain of many listening rooms and allows fast and precise bottom end when used in the right position in the room.

The binding posts are 4mm banana sockets, mounted on a metal plate.

Those banana sockets use very little metal internally to guarantee the best sound – that’s one of the nice ideas of the original design and better than using very expensive “High-End“ binding posts with litte metal but a high price tag.

Those single wiring sockets feed the amplifier signal to a crossover that sits on the rear panel of the speaker.

The original crossover needed very little components and was extremely simple, the new Epos ES14N follows the experience of the last 20 years that electrical parts are easier to control than mechanical filtering in driver units.

In earlier days, before Klippel, the multilayer coil of the original woofer was designed in a way that it rolled off the woofer with the weight and the high inductance of the windings.

Epos driver audio venue

The 36mm voice coil of the unit was a relatively straight forward choice.

It uses a 18mm long 2-layer winding of copper wire on a non metallic TIL former (TIL is a Glasfiber/Epoxy mix ).

The shape of the magnet was optimised, using simulation, to have the best linear BL behavior and a very low variation in inductance over the movement of the coil.

This gives you the lowest level of linear distortion and Intermodulation distortion and is clearly different to the magnet system used in the old days. variations.

The main magnet is a Ferrite type, the flux compensation magnet reduces the stray field of the magnet and set the right BL for the cabinet size.

A Neodymium disk on the pole piece made the BL more linear and a metal phase plug helps to move heat from the coil.

All the parts are mounted into a very strong glass filled plastic basket made from scratch.

The material was chosen for the combination of stiffness and good damping.

A 7“ driver designed for use in a ported speaker plus compensation for higher resistance air coil.

Choice of Polypropylene as cone material was set from the beginning.

Polypropylene is a nice material – very consistent, can be made with different filling material like MICA and it can even be injection moulded for funny shapes or variations in thickness.

Combined with a low damping rubber surround, it delivers lots of dynamics with very low colouration 28mm VC for better performance at the lower end of the tweeter range.

Epos tweeter

The dome itself is made out of an Aluminum alloy with additional ceramic coating to increase the stiffness.

Together with the fabric surround and a shaped Mode control ring, the resonance peak of the tweeter is around 30kHz, shifting it out of the 20kHz limit of human hearing.

The magnet system uses Ferrite magnets and an improved cavity combination to minimize distortion. Ferrite is the better material for a tweeter if a small size is not needed.

It offers a lot more “air“ behind the dome and the surround and avoids compression and harmonic distortion because too small cavities.

A copper cap in the magnet reduces distortion and increases level at very high frequencies.

The tweeter used no waveguide for sound reasons.

To protect the dome, an oval asymmetric mounted perforated metal grill has been added.

This part is not removable and was used during the voicing of the speaker.

The massive metal plate of the tweeter is only touching the cabinet on 4 points around the screws (idea taken from Roy George of NAIM with his blessing) to reduce a transfer of energy between tweeter and cabinet baffle.

The tweeter has its own cavity in the cabinet.

To give the speaker a home to sit on, a dedicated stand is available.

The middle part is made as a massive wooden bar, combining 4 layers of wood, glued together with same damping glue used internally in the Epos ES14N.

The top plate is a double layer steel plate with a Bitumen layer in between and the bottom plate is a thick steel plate to hold adjustable spikes.

The Speaker can be shipped without a stand, so other 55cm high stands can be used as well.

OVER 32 YEARS … 1983 Epos Loudspeakers was founded in 1983 by Robin Marshall. Robin was responsible for the companies’ iconic Epos loudspeakers in the 1980’s onwards. Robin’s “trademark” was to make sure the drive units integrated well and therefore he was able to use simple crossover designs. The models of those times were very well reviewed and the brand had a big following. 1988 In 1988 Epos was sold to Mordaunt-Short who had been bought by the TGI PLC group in 1987. Also in 1988 TGI PLC acquired the Creek Audio brand. Epos loudspeakers and Creek Audio electronics were sold side by side worldwide under Mordaunt-Short’s management. In 1994 Creek Audio was sold back to its founder Mike Creek. 1999 In 1999 TGI PLC group decided to close the Epos/Mordaunt-Short operations. The Epos loudspeaker part was sold to Michael Creek, the owner and managing director of Creek Audio Ltd. 2020 In 2020 Creek sold the Epos Loudspeaker brand to Karl-Heinz Fink, founder of German speaker designer firm FinkTeam and also head of acoustic design consultancy Fink Audio Consulting. Karl-Heinz had always been interested in the Epos design philosophy and knew he could update that philosophy with more modern design and engineering techniques. In an interview with Robin Marshall made in the 80’s Robin said clearly that he designed the speakers based on the ideas and know-how he had at that time – not more and not less. That sounded like the Fink Audio way……trying to stretch boundaries and not copying the past.
