Is fiberglass insect screen mesh transparent enough? Router a groove along the back frame edge and use the rubber gasket and screen roller to tension and hold in the screen. (I haven't tried this, but I can imagine the corners being a problem.) The frame could friction fit (using some foam weather stripping) over the outside vertical edges of the front baffle.

The biggest problem, I believe, with grills are the frames more than the material. There is a large variety of "acoustically transparent" material. I've often thought the method of running fine "string" down the front without a full frame was a good solution. Whether this provides the protection you're looking for, I don't know. I can't recall the manufacturer that uses this method at the moment.

Sonus Faber has elastic strings strung vertically in front of some of their models. I happened upon them during a field trip to Magnolia the other day. Salesman blathered something about designer being inspired by string instruments. Well, I don't see the point as they offer no finger-poking protection whatsoever and hardly any visual obstruction. That qualifies as a gimmick to me.

But tighter and closer strung strings seems more useful, but still not determined toddler-proof. Pantyhose would be better.

PS. Toddlers (and teenage boys) instinctively want to touch nipples.

True, true.
Like I said, the frame is the real problem. Anything that can be done to minimize the high frequency diffraction caused by it is a plus. Rounding the edges, a "soft" frame (not sure what that might be) or getting the frame on the same plane as the front baffle. That would be a neat trick if it looked good at the same time!

All this talking about frames has made me think that what I need most from a grill is absorption of early reflections. So maybe something like a foam lens hood with adjustable wings. Or a thick piece of foam of variable density.
I feel sorry for people who need to provide finger protection. And I think by painting the baffle flat black, the speakers blend with the background better. I don't want speakers too loud or busy, visually. I don't see the point of the Revel Salon grills, either, as proper grills have to hold out a purposeful person.

The experiment to turn these felt absorbers into grill carriers stalled when the speakers were set aside for better ones... the many coats of PVA on the back wasn't enuff to stiffen them sufficently -- i shall return to them as i feel it is worthwhile figuring out how to make it work (the felt packing taped to the box front was an improvement)
