Here we are, your ESL-Specialists

 

Welcome to the intro page of "Doc" Reiner E. Römer. Yes, the man from Aachen/Duisburg. Hello to those who were possibly searching for R.A.E." "Römer Audio Equipment", and reromanus.

 

Our main concern is still the same since about 40 years... electrostatic-, ribbon- and horn-loudspeakers.

We are still on top of technology, improvement and progress.

 

 

What we can do for you...

 

Since more than 40 years, our activities are very widely spread all over the subject of electrostatic loudspeakers.

Our main concern is manufacturing, developing, repairing an upgrading of electrostatic loudspeakers of all brands, including magnetically driven panels. .

We also produce and repair true ribbons of all brands, including Decca-Kelly and Magenpan ribbons.

A side effect of this work is the capability of being able to repair all kinds of planar speakers, from full range speakers to tweeters of all brands.

 

Shackman ESL Loudspeaker Technology

 

Shackman ESL-MHT85 with OTL tube amplifier

 

Alex Shackman, former audio engineer at the BBC and in the army, worked together with Peter Walker of "Quad" on the development of a modern electrostatic loudspeaker.

His idea of building an ESL panel with a curved shape was a revolution in audio history, still commonly present on the actual audio market from several brands, amongst others mainly "Martin-Logan" and Bowers & Wilkins, the famous DM70.

Amplifiers for Electrostatic Loudspeakers

 

OTL Transistor amplifier for transformerless output to ESL

 

We are specialized on building transformerless direct coupled amplifiers for driving electrostatic loudspeakers.

There are two principal versions of the Shackman Reromanus OTL amps.

V-Typ-WR

The V-Type and the T-type. The first one is based on tubes, The latter is based on High-Voltage Transistor technology.

Both types deliver output without the use of a step-up transformer. These amps are available ready to go or as kits.

But we also have step up transformer for sale, including original spare transformers of a variety of brands

 

 

 

Repairing, Upgrading of vintage electrostatics

As we are producers of our own brand of electrostatic loudspeakers, we are in consequence able, to repair all other brands of planar speakers and electrostatic headphones, like Koss, Micro or Jecklin.

We are proud to be able to repair even loudspeakers with curved shape, like Bowers & Wilkins, Martin Logan and SoundLab

Are you getting more and more awful listening sessions with your old but beloved planar/electrostatic loudspeakers?

 

Looking for rapid, decisive but fair help? With us you are surely right.

But, nevertheless, be aware... really repairing electrostatic loudspeakers is not that very easily done.

 

After all..., why, the hell, trusting in our service quality and reliability for giving full renaissance to your most valuable ESL loudspeakers

 

Simply..... because we are aware of things which really count in these matters:

We master these matters!!

 

 

 

Supply the ESL Community with tools and material for

DIY

We offer and have in stock tools for building your very own ESL panel or try your own ESL repair

 

* Foil

The stock of SHACKMAN diaphragm types "On the roll. There are different materials, un coated and coated, different sizes and different thickness’s. Please refer to our price list for more details.".

 

 

* Coating

The sensational brand new MOP-bi-activated PA-Coating for all kinds of ESL diaphragms. Stable, sure and reliable "for ever" up to 10^11 Ohms ideal surface resistance for all polarisation voltages.

 

 

* Glueing

After the correct coating liquid, the glueing procedure is most important.

Probably the best adhesive for gluing Polypropylene and Polyethylene. The brand-new reromanus PMU-2019. The best one, we ever had in hands.

 

* High Voltage Cabling

After the correct coating liquid, the glueing procedure is most important.

Probably the best adhesive for gluing Polypropylene and Polyethylene. The brand-new reromanus PMU-2019. The best one, we ever had in hands.

 

 

 

Repairing of True Ribbon Speakers like Jordanov, Decca Kelly and Magnepan ribbons

 

Decca-Kelly repair with frame produced by reromanus

We are specialized on repairing true ribbon speakers. We not only repair Decca-Kelly but also produce the ribbons and frames ourselves. The frames are made of long lasting material without any deformation over the years. We are also able to repair the ultra-long Magnepan true ribbons. and frames ourselves. The frames are made of long lasting material without any deformation over the years.

 

We are also able to repair the huge Magnepan true ribbons. and frames ourselves. The frames are made of long lasting material without any deformation over the years. We are also able to repair the huge Magnepan true ribbons.

 

 

Repair of Focal, Podszus-Görlich and other Dynamic Speakers, as well as magnetic planars

We offer repair services for several famous dynamic speakers, including Podszus Görlich, Focal, Magnepan, Bowers & Wilkins. We also handle all kinds of true ribbon speakers. These vintage speakers are very rare and spare speakers are not available.

 

Unfortunately original Podszus-Görlich and B&W DM70 drivers are no longer available. So repair is the only solution to get them back to work correctly.

 

 

 

Repair, adjustment and upgrading of vintage mechanical Audio components
