I'll definitely post a follow up, but it will be a while. For now I will say that the concern about the bass alignment is valid, but a variation of +3 / -2dB really isn't a big concern to me. The actual in-room response I have measured on speakers that are known have very flat anechoic response curves has varied by much more than this, especially below 200hz. As I mentioned in a previous post, in all fairness to these drivers I need to give them 100 hours of break in time and then do a critical evaluation.
