We have now released the replacement for the elderly but respected ESL III and ESL IIIb speakers. The new speaker is
called the ESL IV
(I know, quite unimaginative!)
More information and updates are now available on our 505 mini panel page. Click on the link or on the Mini Panel box to the left to read about it and see what it looks like.
We have updated the 505 page with some more information from a 505 user, click here Greg's Project to see Gregs project.
Follow this LINK to read a recent review for our new 3 transformer version of the Acorn ESL.
While we have endeavored to maintain our low pricing, inevitably there are some increases to be made due to raw material increases and the drop in the Oz dollar. Be sure to refresh this page from your server so you see the revised pricing.
Note, we still have some spare parts for owners of ESL III’s and IIIb’s available and still offer support (as always).
If you own some Quad 57 electrostatic loudspeakers that are in need of repair we have posted a complete repair story from Meinolf, a client in Germany. Click HERE to take you to this page.

Exciting new product, the improved 505 panel and dynamic bass system.
Following the unexpected unavailability of the 440 mini panel ESL we decided to create our own improved version. Our customer feedback on the 440 product was very good indeed with the only criticisms being low sensitivity and a narrow dispersion pattern.
Because we started out with a clean canvas we had the freedom to design to our wish list which has led to a very nice loudspeaker. The panel has grown in height a little going from 440mm to 505mm, width has reduced from 168mm to 150mm. The panel thickness has reduced from 8mm to 5mm allowing a very slender frame to be used.
These changes plus changes to the conductive surfaces within the panel have resulted in a panel with excellent frequency response, dispersion and sensitivity
As with the 440 mini panel, the 505 ESL panels are supplied ready to be mounted in a baffle of your choice be it Perspex, glass, timber, lacquered MDF etc. They come complete with a ready built and tested power supply and audio transformer. All you have to do is mount them in a baffle, connect them up and play some music.

June 2019 Update
One of our Italian clients has been kind enough to fully translate our Quad 63 - 2905 repair manual into Italian and has made it available to us to assist Italian repairers keep their speakers running properly. He has also supplied a brief description of the repairs he made and the equipment he used. The English version of this can be found HERE. Italiano HERE.
Final 0.3 and Martin Logan owners may find this of interest
We are in the process of upgrading our very well respected Acorn full range ESL to eliminate the plastic CNC support panel. The speaker will use 4 discrete panels on each side in the near future. This allows us to increase the bass panel area by around 15% without changing the width of the finished speaker.
I won’t go into this too deeply here but the new Mid-range / treble panel has been used very successfully in a pair of Final 0.3 speakers that had suffered panel fade.
The new panel is 920 x 200mm and will fit in the Final frame easily, it will also fit some Martin Logan models. No changes are required to the drive electronics.
Click HERE to see the panel fitted to Final 0.3 speakers.
