Late to the thread, but another vote for a grill.
I know you have technical and personal reasons for insisting on "lids" Mark, but a cover might as well be made of mesh than perspex and serve the same purpose, as well as serving as a way to listen non-seriously while kids are in the room (or not listening while kids are in the room alone).
A light plastic frame and a flat fine mesh, attached with magnets would serve the purpose perfectly.
If you don't make them people will just do them on their own, I know I have, but not as good looking and style matching as you could.

My listening time requires absolutely no protection for my speakers, I'm alone. For the rest of the time the drivers need protection, like a door that comes with a lock!

I have two young children and experience has shown me that nothing is sacred, nothing is predictable.

A removable cover, now that's something I would pay for.

well, no, the children are sacred (until puberty ), and while their propensity for chaos is certainly predictable, the manner in which it's manifested definitely is not

geeze, I wonder if my mom still feels the same way 60yr later

This was done by my cat 2 months ago.. the cone it's ok, i can't hear any difference in sound, could this present any problem in the future?

Right now i have airplane scale models placed on each speaker so the little beast doesn't have a place to jump up (maybe also a metaphor about the music flying you up in the sky? )

Re grills, should they remain attached during system operation, they undo all our driver design efforts by interfering with the power-train's dispersion. Having damaged a cone or 2 at home while cleaning over the years, I naturally sympathise with the protection issue, but I won't get involved in grills as they mess up driver emittance.

Personally I thought my cover idea was good. For re-introduction, it needs positive support from a good number of members to make production viable. If we see more than 40 posts in "real" support of the covers and the dealers are convinced, maybe we could re-introduce them.

Thanks
Mark.
I to will need covers or grills for my newly built speakers,or they will not be able to go to there new home in our living room, im sure it will only take about 30 seconds for my grandson who lives across the street and visits daily to find, check out and destroy one of the10.3m drivers

Has anybody actually tested the response and dispersion of speakers with and without different forms of grilles, such as proper cloth on a frame, perforated metal, or wire guard (Boxer fan finger guard)?
I don't need to see the cones move to hear the sound, and some protection can save the speakers from accidental damage.
I don't want another MDF / Plywood type argument, just some information.

Dave Rosgaard took such measures of a small TMM system ( CHBW70 & ERT26) for Bob Reimer ( CSS)

certainly some effect can be noted, which no doubt "grilles" could be designed to minimize

but of course the real argument will be the subjective "how much of that can you actually hear"? - such as - please use all the same colours of twisted pairs extracted from CAT5 network cable in any give pair of speakers, because of the slight difference in twist rates - really?

Let's be honest, short of a perfed or screen metal grille, the only protection that a cloth grille will provide to inquisitive fingers is that of being out of sight - and for some folks there's the WAF of -"if it's in my space, dear, I don't want to see any cones"

Perhaps a foam "lens", concave to encourage dispersion, and with a few threads of metal wire behind it to stiffen it a bit. And of course magnets to attach to the screws.
Could be made cheaply in a variety of colours and have very little negative impact on the sound.

This would be light, easy to put on and take off and would prevent accidents and inquisitive fingers.
But of course in the end not real malice, child or grownup.
From a certain point on the responsibility if with the grownup for the upbringing.
