Then the felt rings might be a solution in your case, otherwise you can try and make those rings out of toilet paper. Know sounds weird. Did that with my hd 560 their supposed to come with some paper/cellulose rings on them that cover most of the driver with a very small open dome in center. Since I couldn't find a replacement anymore tried toilet paper, took 5 layer on cut a piece to shape and tested then removed a layer and tested again, and one more time ended up with 3 layers I believe.(you can plie the layers apart quite easily making the exact thickness needed.)This is basically my experience with the ref II, even after all the tinkering, which I why I feel I'd probably have a more comfortable listening experience with some rings. Maybe I'll try popping in the ones from my 560 at some point. I have tried it with normal felt, which killed the detail and staging, but I imagine its a bit different to having proper acoustic felt
Might do the trick for your 540s aswell.
