I've used PVA in the past and it's worked well.

I'd agree. PVA adhesive watered down slightly, and a single ply of paper tissue. Use it like fibreglass tissue or matting on car bodywork. Apply a thin layer of pva, put the paper tissue in position, and stipple gently with a bit more adhesive. Don't use toilet paper, though. It's formulated to fall apart when it gets wet!

I'm puzzled over the number of 'delicate' patches being suggested. Isn't the speaker cone supposed to be rigid?

In the past I've used writing paper and PVA to cover holes and even used a bead of hot melt to repair a tear

To me, blotting paper seems to be an ideal patch.

I just try to keep the repairs as light as possible, especially with a small speaker. Often it is the cone surround which is damaged, if it's an all-paper job, and tissue with pva is thin and flexible enough to make repairs in this area.
