Any notable 32ohm drivers that tend to produce less pinna gain then or is it basically entirely down to the reflections caused by the restriction?Not that I am aware of.
The maria and maria ii also have that.
Sorry, no one has a resource like that. You may find some stuff in this thread or elsewhere. But the problem is everyone's rigs measure a bit differently and there's no repository that you can reference.
You'll have to experiment. Usually more restriction raises pinna gain (ie thicker foam/cotton). Problem is, if you go to far the other way it may sound flabby, wonky or otherwise weird.
