I bought a pair of c51's with the LX5 crossover (pictures attached). I read that the older ones before ?1973 with alnico drivers were better. The serial numbers on the cabinets are 53154 & 53155. The serial number on one of the LE15As is 16387. They look great, really beautiful covers. I think they could sound better though.
It seem like the mid lows are kind of muddy. They've been sounding better, but I'm not sure if it's the surrounds starting to loosen up from having sat for years, or if it's my moving the speakers around. They probably need surrounds. And I probably need to see if I can test the specs on the crossover components. If I get to dumping money into the crossovers, would that money be better spent replacing the crossover with a more modern design?
I also have a pair of L55's the are a little rough looking, but they sound very good. The LE14As in those also need new surrounds.
Thanks,
