He had a previous version that used a different ribbon and they were highly regarded as well. I have 3 boxes ready for some A/V-1s. I wonder if I could modify them to take N2Xs?
*edit I just looked at the plans and the tweeter positions are different, so I don't think I'd be able to make it work. Maybe I will have to get on that list as well, as I have not heard the N2Xs. Now that I have a radial arm saw and a big empty garage, I can start doing some projects of my own
