Does DOY stand for Day of year? I bought my CF-3s and a KV-4 new in 1997 and thought they are rev. 2 (from memory) only one serial number is barely legible 241599267. Which makes them rev. 3? I have done extensive upgrades over the years with bracing, installing a pair of EV 1506, port extension etc.. I'd 'like to rebuild the crossover as well. I have a lot of memories with these speakers which keeps them in a system that has moved up in scale since then.
