Looking for the closest sounding current Celestion to a 70s Celestion G12H Blackback 55 hz but in 100 db sensitivity instead of 96 db. But I think I want to try a 75hz this time around. Going to pair it with a pair of Cream Alnicos in a 412, close back of course. I guess that would be a G12H-30 Anniversary but not sure . Thanks in advance.
