Hi Jim,

It's a pleasure for me to see how many persons were involved in making these important speakers! At this moment I've got 2 paisr of CIZEK model one and a pair of model 3 which I restored for my Mother.

I've never listened KA1, but there is an audiphile in Spello (Perugia, Umbria) that is near where I live (Fano, Marche), who has this model and perhaps I will see and listen them in the future.

I think that the ring of tape around the woofer is a pure protection, like that you can see above the tweeter metal part and that could be removed, but I'm not sure.

All The Best, and Thanks for Interest

Paolo
