Magnepan “X” upgrade program

Curious if one could send in a pair of LRS’s for the x upgrade or if it only applies to newly purchased speakers?

This still seems very high to me. I mean how many capacitors and coils do they have, several hundred? Even adding wire and connections, they are not adding 100 feet of wire.

I'm a little foggy on why the X program would cost the same across all the models? Or do I have that wrong? How can the upgraded parts possibly exceed $500.00? I get labor and profit margin, but wouldn't parts be more expensive as you move up the range?

Why would you want a magneplanar (stock or modded) when you can make an inexpensive Dipole two way speaker that is superior for very ittle money? Use the 12 inch woofs used in the Caladan and Spatial X4 and use GRS planars above them...crossed over at 400hz. Way more dynamic....way more sensitive.....way more exciting. Please listen to the sound on this Youtube video about the Spatial X4.......however this Beyma AMT that you hear in the video is crossed somewhere around 1K......now imagine a dipole planar crossed at 400hz......same woofs. The X4 in this video is the older one.....now updated with better xover parts and now costs $9800. The speaker you can build will not cost more than $2K. Listen to the bass on these tracks. 2 12 inch great woofs on an open baffle are seriously good. I will have my version up and running some time this week.....this is getting exciting!
