Nothing like getting a nice pair of speakers only to find a small hole in otherwise good grills. Here is my way of fixing. My apologies if this has been covered before.
I was working on a pair of Bose 301 speakers. There was a small hole in the fabric.
The hole was big enough to see from a distance. The rest of the grills were just fine.
Got out the handy can of Weldwood gel contact cement and carefully buttered the inside edge of the hole (place a small sheet of wax paper underneath for accidents). I used a toothpick to apply the glue.
Let the cement set up as per the instructions (10 to 15 minutes).This photo below shows how little I used and how it is on the inside of the grill material.
Then used a couple of scribes to gently pull the material together from the inside, making contact with the tacky buttered edges. Work slowly so as not to bunch the material and create a fold or wrinkle.
The contact cement should grab and hold. If it doesn't come together completely, lightly re-wet, let glue set up and try again. Usually it will hold the first time but this pair took two tries. If you look close you can see the patch in the corner but not visible from 5 feet.
Some grill material works better than others. I did 1\4 inch hole in a pair of Rogers LS2's with black cloth and up close you cannot find the patch.
The trick to a successful patch is lightly paint the inside edges of the grill so the glue does not soak through to the front. Once the contact cement sets up I do not think it will penetrate. Do not press the material as that would squeeze the glue through the material.
As mentioned the success is material dependent and size and shape of the hole. If he hole has a lot of stringy edges carefully trim and glue.
I have done some fairly large holes but a dime size would be the limit. Bigger than that give it a try - you're going to have to replace the material anyway.
