I too am currently in the process of building the andromeda mk-II speakers. I have a question about adding the magnets to the back of the scanspeak drivers. When I added mine, they wanted to slide off about halfway to the side. Did you remove the back plate from the original driver first? I had to put on the epoxy, then fasten a belt around the magnets to hold them in place while the epoxy cured. One lined up perfectly, the other is about 1/4" off. I did NOT remove the back of the pole-plate first, so there is a small gap between the magnets. Other than that, all is going well. I am making the top part first, then will do the bass enclosure in a few months due to budget constraints. Tony told me that this would be no problem, just to take the woofer part of the crossovers out right now, then add them in for the completed project.
Any comments would be great.
