Now that I have heard both the 3.7 and 20.7 in the same room with the same electronics, I have to say that the 20.7s better the 3.7s enough out of the box to warrant the upgrade.
The 3.7s are a great speaker and a steal at their price point but to my ears the 20.7s offer a fuller richer sound, above just "more bass".
Everyone needs to make their own decision on whether the price vs sound differences justify the upgrade, but for my part and situation, I have no hesitation saying yes.
Regardless, if you have the chance to hear these wonderful speakers, do yourself a favor and give them a listen
Unless they re-release a 3 panel Tympani type speaker, I cannot imagine ever looking to change them out
