Hey, welcome back!
I wonder if the 8.35s can be modded into sounding even better or are the driver's surrounding already acoustically perfect?
More specifically though, I wonder what do the ribbed tubes do (beside protecting the wire that goes between drivers, obviously). They open inside the cups so if I remove them there's bound to be some leakage, but what if I just plug the holes? Will it make the sound less open? Will it matter at all?
Yes, I'm still contemplating my headband mod
I don't think there's a hole actually! Didn't see a hole when I opened them up for the cables. And besides doing the cable mod, there is little to be won with mods. And I'm not even sure if the cable mod did anything, I think so, but never got to a-b it with a stock 8.35D.
