Frequency Response graphs?

Hey guys,

 

I am CONSIDERING a speaker swap on an EL84-based combo I have. The company that made it recently went belly-up, I think. However, I do have a graph of its freq response, and also have those of some Eminence models I've been considering. 

I would LOVE  to check out the graphs for the WGS Liberator 80, ET90 and maybe the G12c and G12c/s. Are these available?

Thanks, danke, arigato, gracias...
