Just along the outer edge. Some people also glue it to the retaining ring, or simply use the compression from the ring to hold it in place (stretch nylon over, snap ring in place, cut off excess)

I think they intentionally did not notch the wood so that it wouldn't create potential areas to "seed" the formation of cracks in the long-term. Small carved slots in wood is a no-no.

Makes sense...I guess it leaves it to the people to be creative. You could forgo the ring altogether and use the small space to create your own grill holder.

Maybe alternatively I can line the inner rim of the wooden cups with something that will stay on, so that the ring sort of wedges in solid with just friction. The bevel for the grills/retaining ring is not a lot of space though.

It' gonna add some weight...but you could get a 3 or 4 piece 90* aluminum sheets with holes, tape it inside with 3M Extreme double side tape, and either use velcro or a nut/bolt on one side and poke the thread through the grill with another nut on the other side. I would imagine the velcro option being much lighter.

That sounds like an awfully convoluted solution for a simple issue lol.

Haha yea but it'll probably work well and offer good stabbing protection vs friction. Does the wood have a ridge to hold the grill?

Yeah. Actually I realized that because wood has some give to it unlike plastic, you can just cut the grills just big enough that it stays in with friction very well (the spokes at the edge of the grill mesh all very slightly dig into the wood and it becomes a very secure fit). No need for the retainment rings at all.

I was wondering about that.  Thanks for confirming.

Recently did a grill mod on my HE-500 and was really taken aback at how much of an improvement it represented. It was really good already but the more open grills I used widened the soundstage and made the treble very articulate without being overboard -- I'm really loving it. My mod was very similar to Armaegis (previously posted -- see below) and quite likely used the same materials (grill from a waste paper basket $3, plus ladies' sheer pantyhose underneath $3). I did not use glue for the panty hose; I simply stretched the pantyhose around the grill and found the edges held it together quite nicely and I simply trimmed around it. I used pantyhose for a dust cover because I prefer the low maintenance approach, also the totally open grillless version sounded a little too bright for my taste. The grill plus the panty hose were just the right balance! Fabulous mod ... along with going balanced 4-pin XLR for the cable and using speaker amps, this has been the most telling and easiest mod to perform. Kudos to Jerg and Plin for the mod. Now I'm left wondering just how close this has brought the HE-500 to the SQ of an unmodded HE-6. Has anyone done a comparison with this?

 

Here's a pic of my finished version; see spoiler for Armaegis' version.

Combined with my damping on the front side, these are practically dark sounding now.
