I watched a tear down video of the Neo10 and while I assumed that it had 9 magnets per section, its actually 7, and unlike the Neo3/8 they are longer. This means there is only 3 rows of them, not 4.
Meaning the 42 count it most likely correct, with 21 per side, like the GRS-10" page states.
Makes me curious if a pair of "Pseudo Minis" could be built...
A pair of GRS-3s & GRS-10s would cost about $320...
I believe Jay still has some Super Mini flatpacks going for $250+ shipping.
Then depending on the cost of a crossover, I'm guessing you could build a pair for $800-ish or go with more "budget" options to keep with the "Pseudo" theme, based on Danny's schematics for maybe $700?
Only snag would be the GRS-3 using the weaker 6 magnet PDR design instead of the original 10-magnet model, it might require a redesign of the X-over?
I think it would be a "fun" build, but I wouldn't be able to enjoy them, esp since I already have my XLS built & the NX-Studios still in progress, and don't have the space to enjoy them properly.
