Well, it’s finally here! The 505 mini panel has been running now for around a year and can be released for general sale.

Click on the link or on the Mini Panel box to the left to read about it and see what it looks like.

Exciting new product, the 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.

 Goto to our MINI PANEL page for further details.

We will provide quotations for freight or postage of components based on the weight of the package. We will normally quote registered airmail or Pack and Track for overseas small packages and will give a courier option if required.
