Agree with french fries. The GH's do produce bass down to about 45hz., the GE's will go down to about 40Hz. In order to get a fuller sound in the bottom end, you will need a subwoofer with any of the G's. As to the Amati's, I don't think they image as well, nor do they disappear as well into the soundfield, but they are more full range than the G's. I suspect in order to really produce 'scale' then none of the SF's can do that as well as some of the very large speakers in a very large room. Thinking of the Wilson XLF's and the big Magicos etc.,here.
