Re: More to a measurement then the transfer function?
Hi Peter, yep...I caught the rubber you added.... and exchange between Mark D and you, back when posted off-axis plots for the DIY60.
I've been hoping to measure stuff like that. You know.. trying to synchronize brain and ears 
Your DIY 60/90 designs have turned into such great learning platforms....they respond both subtly and boldly...
I'm hoping to initiate a new thread with some phase questions, when it comes to phase relevancy.
Experiments with FIR and what feels like making phase and magnitude overlord....rePhase/minidsp ......are making me both believe in what the the transfer function shows, and at the same time question it too...
To Dave, OP, pls pardon if I've overstepped direction of your thread....I realize my first post was not relating to what you were asking about...
