Konstantin69- Very interesting and informative response. Would a small anechoic chamber be necessary for this? Sounds like you have this pretty well thought out, have you actually done it before? I had a feeling someone was going to point out that a condenser would be better for this. Very good point about loading, didn't take that into consideration.
A small anechoic chamber doesn't hurt but not necessary if you're in a quite environment, I actually use an old closet lined internally with some leftover acoustic foam from the studio.
I've done something similar ages ago but for measuring the FR impact of different earpads.
Your idea about measuring the impact on the overall FR that different shapes and dimensions in Grado's acoustics chambers is brilliant and something that crossed my mind a few times.
I got wood cups from different vendors, some I like more than others, BUT my favorite cups do not "mate" well with all drivers and some drivers "mate" better with "lesser" quality cups, it's a "mix-and-match" situation for best results, maybe it's time to investigate further, when time permits.
@thelostMIDrange You are not alone...
You got the wrong "message", when used as @ecdarby proposed, i.e. using one driver as the source and the other as the mic in order to null out their FR for taking measurements they must be absolutely identical, when used as headphones attached to each ear I don't sweat much about it.
What makes you think that both your ears hears the same? In some frequencies the difference can be as much as 7-10db, especially if you're over 25-30years.
Let alone the fact that your right ear hears differently than your left.
