[QUOTE="Hennie, post: 23924, member: 20"] A known problem with this kind of coaxial - in a two way system. Works better in three way systems - excursion of the midrange cone is reduced. Another problem with this kind of coaxial is that the cone is much softer than any stand-alone waveguide. Deformation is inevitable and the cone is not rigid in the tweeter operating region. Radiation patterns are affected to some degree, but more important, you are limited to very well damped cone materials. It may well be the reason Kef still sticks to polypropylene (not my favourite cone material). Seas has stated that they won't do a coaxial version of the Excel drivers. [/QUOTE]
