Anyone heard EGM Planars

[hal55]

http://www.egmaudio.com.au/wp-content/uploads/2017/04/EGM-AMT-65-01.pdf I can get this planar tweeter locally for $70 Australian.Have never heard of the brand - if anyone can shed some light on them it would be appreciated and even better if anyone has heard one and can give an opinion on their characteristics and whether they are worth the money that would be great. The midbass I am tempted to use is the Usher 8948A, pdf as follows

Again, any comments on suitability of this combo greatl appreciated. The Usher seems to be usually crossed over about 2.5Khz and the EGM has a lowest recommended crossover point of 2.7khz, so I'm hoping they can be made too work okay.

Thanks for the advice, any comments re sound quality and character of this unit as opposed to say the Fountek Neo CD3 - that looks like one nice tweeter for not that much more money.
