between the Heresy and 2 Pi.It is very much what I expected:
2 Pi - disregarding labor, materials for the 2Pi was less than $275 total.  For that price I could not imagine a better new speaker.  It is very efficient and a surprising two way.  The Eminence speaker was an instant success to my ear.  I still have some difficulty with the tweeter in a comparison with the Heresy, but when not comparing the two it is a reasonable solution.  As a speaker I intend to give to my daughter that was more of a 'carpentry practice', I was more than pleasantly surprised and may well keep (move to my office) until I think her ear deserves it (grin).
Heresy - I still have an affinity for the two horns on this speaker and most everything above 700- 800hz is a joy (at my age - not having much above 16Khz seems to be of little relevance).  As expected the stuff below 700hz is not my favorite part of this speaker.  
For overall performance, I will be staying with the Heresy.  However, there BR portion of Wayne's design is a very pleasant surprise and is why I will be making something akin to a Pi aligned three way with horns for the higher freqs and BR for the lower freqs.
Also - even if comparing with the used market, the 2 Pi can be significantly cheaper than Heresy II and an interestingly equitable performer, especially in the Low freqs.
