    i have already built and tested the first prototypes.
    as expected, the spatial reproduction of the sound stage is impressive, however, an unwanted typical horn related sound coloration due to the cones can be heard. furthermore , the overall efficiency is reduced and the high frequency level is decreased. i can deal with some negative aspects of these omni-directional speakers, especially , because the resolution is still ok, but the sound coloration has to be corrected. if i have time i will experiment with the shape of the deflectors (cones) and tune the distances to the drivers. i am convinced that the coloration can be widely managed, since there are many reasonable omni-directional speakers available in the market, but considering my limited knowledge in building speakers and my available time as well as absence of a workshop, i am afraid that it takes me longer to do that :-) .
    i will keep you informed about the progress if any ;-)
    
    cheers

    kind regards, mamal
