Diaphragm replacement, 2 watt or 5 watt K77(M)?

[KT88]

 

The old K77 Alnico have a 2 watt load, the K77M supposedly can cope 5 watt.

If I put new diaphragms in an old K77 Alnico, earlier a 2 watt load, like the new diaphragms in the link below, will the tweeter have a 5 watt load? Or does it have nothing to do with the voice coil?

BTW I am very glad that I found this offer. Over the years, as far as I know, the problem was that there were no replacement diaphragms of reliable quality?

I thought whether or not they had beryllium leads was what made the difference between 2 wt and 5 wt K77s.  I thought most of the F models did not have the beryllium leads.  Does anyone know for sure?

 

Also, I heard that the company in the Philippines that made the F didn't get it right at first, but did, later.  Again, does somebody  know?

I do not see how it could be anything other then the voice coil. The voice coil is what burns out when they blow. Know this from experience. You should have a 5 watt tweeter when you switch.
