I nearly crashed my bike yesterday when I saw this at the side of the road in a "Free" pile. Thankfully one of my kids was home and brought the car to pick it up.
It sounds great. All the drivers seem very lightly used. I've never heard the 2405 before. Incredible. My plan is to sell the K130 and N2400 and buy a second 2405 to replace my 075's in my living room rig. From what I can tell the 2405 and 075 use the same physical mount.
How important is it that I match this Alnico 2405 with another Alnico 2405? Flux is flux, right? Would there be a difference with a ferrite 2405?
