Stick your face in the sunshine and sing. You roll find the body he's a resonant peak somewhere around a low F#. It may be higher or lower, which will affect low end tone.

I have one guitar with a resonant peak at G and it is the one out of my collection with the least low end, especially evident on the low e string. I also have one guitar with a peak at a low e. It has massive low end, sometimes too much. There are many elements that go into a guitar's tone, but I have found this simple peak resonance to be an important factor in low-end power specifically. In my very limited anecdotal experience, the lower the peak pitch, the more the low e string will give up the goods.
