Well, there are a few places that can re-charge the drivers, GPA can do it for sure but it is not practical in my view as to remove the drivers from attic horns and to ship them is more pain then to pay to GPA $20 to re-charge them. The re-charging is truly not so difficult posses and I would like to do it in place. I do not see myself to send the drivers each year but I do not mind to do once a year in house firework and to re-charge the midbass magnets. Also, there is an attitude thing: the assholes who recharge the drivers never give you the measurable data of magnetic force before and after. I call them assholes as the last time I sent my S2 to be recharged I did explicitly requested the numbers before and after and I did paid extra to do the measurement. The guy who did it told me that he “just forgot to measure it before”. Thank you very much, the moron! I wonder if he goes under knife to a medical procedure he ask his doc some evidence that he is in fact sick?

Anyhow, I need to find at some old supply sale some used chip device like this:

Then I will be able to do something like this but skipping the ugly part with caps, charges, and commutation…

The Vitavox magnets are well exposed and I will wire 20-30 turns of thick wire and I think I will be fine. All that I will need to do is figure out the polarity of the coil, I am still thinking about it. BTW, would it be possible to rent such a magnetizing devise? It probably cost 2-3K it means that it might be rentable for $50 a day. That would be phenomenal!

Meow?
