In the absence of anything else, the feedback system is a decent gauge for putting people on the loaner program as it has established a certain level of trustworthiness in the community. A name & address aren't really binding in any legal way. The "proper" method would be a bunch of verified/notarized paperwork etc which is a lot of hassle and grinds the process to a halt.
That is mind-boggling how much modding went into that. Is that a cork-like material inserted between the magnets? You appear to be blocking some of the holes in the driver itself.

An 8-strand round braid is relatively easy. A bit of masking tape with numbers is a good way to keep track in case you goof up. A double-milloit on the other hand takes a bit more trickery and a lot of time... asdf
Actually, you just have to stack the chips on top of each other and solder bridge the connections. Easy peasy, and it goes up in multiples. The only limitation after that is heat and chassis clearance. Nah man, quadraphonic is the way to go.
