RE: Guessing only....

Well, I'm definitely getting senile, I remembered it as a four-ton press but in fact it's 12:

"As both Wisdom Series driver types incorporate a push-pull magnetic motor system, the brute force necessary to assemble a driver with opposing magnetic motors and pre-energized multiple magnets is indeed substantial – a twelve ton press is required."

Some interesting info in that press release, including the fact that they use the neodynium magnets only in the high frequency section.

Here's a picture of one of the modules:
