Comparisons of David’s Tannoy Westminsters using the Tannoy concentric mid/tweeter with the new ribbon speaker using the custom crossover revealed many things:

The flat panel driver proved to be very efficient with a wide frequency range, 4Ohm estimated 100dB per 2.75v. Not only plenty of highs, very low colouration (judging by the sound of cymbals) and very good transients with no overhang.

Most of the music showed little distortion, with the occasional lapse, but I couldn’t tell whether components other than ribbon were to blame.

Compared to Tannoy’s wide listening position and single point source, the panels where very directional, and imaged well as long as you were in the small sweet spot.

To do justice to Kwan’s panels a dedicated crossover is needed. I could hear a lot of potential, a sytem designed around these drivers will make a superb loudspeaker. Kwan described this as the middle size of three panels, all capable of handling frequencies obove about 320Hz. David is offering to use these panels for some of his hosted !meetings for the Melbourne Audio Club.

Another of Kean’s inventions is the isolation table we tried briefly under the Linn LP12. This made such a difference that the bass was taughter and “quicker” than I think I’ve ever heard on an LP12. Guaranteed we will hear much more of this product.
