Deja vu. I was moving things around the speakers and something fell against one woofer of my LM330s. Like you I thought why did I not have the grills on (usually they were) and this was the end of the speakers.
Not so. You will have a blemish but the utility of the woofer is not shot.
Similar to the response above I used a bit of cheesecloth and Elmer's glue to make a permanent fix. Fortunately the tear is between the frame spokes on the rear of the woofer so you can access a repair on the back of the cone.
Try to get the paper positioned as closely as possible so that the tear section matches up. Need a small brush to apply the glue. I put some glue in a spray can cap (like for paint or starch, etc) and diluted with water just to get the consistency a bit more fluid. This helps to apply the glue.
I just overlaid the small bit of cheesecloth over the tear area and brushed on the glue. When dry I brushed a bit more over the tear area to ensure is was air tight. Don't need to over do the glue or it will soak well into the cone fiber. A thin layer on the surface will remain more flexible.
The cheesecloth (or filter paper above) gives the glue something to adhere to and strengthens the bond without adding a lot of mass.

I thought that was something five year old kids do. Oh, they're into pushing in dust caps. Sorry for your bad luck.

Thanks for driving the dagger deeper,lol
As I've posted in a hundred identical threads, Ailene's Tacky Glue and black tissue paper on the back side. Especially with a clean, narrow cut like that, you don't need to do a whole lot of reconstruction, and the tissue paper will work just fine as a band-aid without adding too much mass. You can add two or even three layers of the tissue paper without being anywhere close to as much mass as something like a piece of coffee filter.

My dad used to use a drop of mom's nail polish on speaker cone holes and tears, if the damage was very small.

I would find a large band-aid, cut off and discard the gauze center section, and use the 2 adhesive flexible end pieces to repair the woofer from the back. Some damage wouldn't need both pieces, but yours will.
I know, kind of a band-aid repair.

I think that's the worst suggestion I've ever heard.

My fix is reversible if the OP doesn't like the result.

Not a bad idea at all. I'd probably want to add some adhesive myself but I like the idea of the stretchy fabric for repair.

There's a hole in my speaker, dear Liza, dear Liza...

Ok, now that I've successfully planted that ear worm.
I did this once to a speaker in my jeep. To fix it, I pulled it out, and from the back smeared on a light coating of gasket maker over the hole.
This stuff:
I let it dry overnight, and it has worked ever since without issue.
If you can get to it from the back, this may be a great solution for you, too.

Seriously, do it this way.

Joke all you want but top gun is right. Cig papers have very good tensile strength for their thickness compared to tissue paper.
