Thanks for the pic of the second version Roamer, definitely worse looking that the first without the mesh on the grills… Looks like a very sad and failed attempt at a twisted pair.
I just a notification mine would be delivered this Friday (I live in Berkeley), so I imagine the rest of the states will see theirs next weekish.
The foam I ordered and linked in my previous post came in and is much coarser than anticipated, lol. I’ll give it a shot anyway. It’s 1/8" thick (~3mm) and looks to have a cell size of a couple mm.
Also, if you are interested in making your own comparison measurements, I just started a new topic showing a super easy way to make comparison measurements for free with your phone - Easy (but rough) frequency response measurements! - #3 by s_beck
