I know roughly how to build grills with speaker cloth, but I don't think that will suffice. I need a metal grill, maybe. Something like Sonus Faber has, but more DIYable.
Can I use some sort of metal netting for grills, i.e. mosquito netting but maybe a with larger holes? Or metal grate? It should stop a pencil or pen. I don't know how well speaker cloth does this.
I was thinking of using magnets to hold the grills on instead of those plastic pins/inserts they have for this task.

Yeah, you can use rare earth magnets (neodymium) with enough holding power that you'll need to pry them off with a crowbar. I think Parts Express has some grills made for PA speakers, they look pretty solid.
Perfect, thanks 😀 I might use them without speaker cloth over them. I kind of like how they look.
I just place them against the baffle and the driver's magnet pulls them with enough force to hold in place.
I stapled some pet proof screen door screen under what will be fabric on top of these grills. I could have used fireplace screen, but this door screen material was free for me. The grills are held on by neodymium magnets. The routing jobs on my speakers are kind of rough. I felt like I had to rush it, since I had limited opportunities for routing because I live in a apartment.

Here they are with the fabric on them. I needed to paint the staples black and maybe the wood also. You can see them through the fabric. The fabric I had before on these grills you could not see through very well. But I will probably redo this fabric later anyway.

aaaaahhhh, those bygone days of rug-rats and diaper pails -- I routinely removed the KEF drivers from my first reflex speakers to retrieve Lego's capsellas, transformer action figures, and GI Joe. Barbie never made it into the tunnel of darkness, however.
I gor some perf metal from It's from Perforated Metals Plus and covered it with some grill cloth. It is attached with some automotive trim.
I Know that when our company specifies steel grilles for commercial nightclub use, the general rule is to use a perforated sheet that has at least a 50% open area.
Obviously the more open area the better. Unfortunately the finer perforated sheets tend to be less that 50% open. One exception is 3mm Hole 4mm pitch that is 51% open. The holes need to be staggered in equidistant 60deg triangles.
Some square hole perforated sheets are more open. 8mm square 10mm pitch is 64% open, 10mm square 12mm pitch is 69% open, but I would not say this is pencil proof!
I feel your pain. Once my 2 Nepwhews came to visit, and immediately on walking in the door, in a synchronised pincer movement managed to push in both dust caps on the stereo. "You take the left, and I'll take the right." 😱

Why did you go with perforated metal vs expanded metal? Doesn't expanded metal have more open area? Although perforated does look stronger and nicer.
The perf-plus.com metal I used is 1/4" hex x 0.285" staggered and is 77% open area. They also cut the sheet in half for me. It made it easier to ship and I needed two pieces for my grills.
I also found McNichols.com has honeycomb 1/4 inch hexagon, 9/32 inch staggered pattern, 0.032 inch bar 79% open area.
