Here are the spec's for the speakers.
The last list of spec's is for the 70th anniversery G12H these have the black sticker with a 75hz cone and are made
in China, if that is good or bad that is up to you, do not confuse those with the U.K made Herritage G12H as these
are made with the 55hz cone, have the plastic GB cover and were "reissued" for the ones who still desired the G12h30GBs,
but would not settle for the 70th anniversery edition, it is interesting to note that they started this line when the G12h
black sticker back was outsourced. Here are the spec's H12m,H12h,g12m(m.i.china)G12H anniversery.
With that said, nothing compares to being able to listen to these in the same cabs with the same settings, which is
a difficult "experiment" to say the least. If your a spec's person these may help you narrow your descision.
