Yes, align all pieces best you can before starting.
If they lined up perfect and this wasn't in the surround area, I would recommend clear nail polish as you wouldn't even need a patch.
This repair will last indefinitely if:
1. you prep the area well
2. you do a good job with the patch

If you do a lousy job and it falls off, then so what, you start again and do it properly this time, no biggie.

Just go to any electronics repair shop, tell them what you are doing and they might just give you a speaker to try it out on. Try and get one with the same style cone/surround.

Nice to hear bowtie's story.

Cal,

If you look at the photo you can see the tear is in the cone area but the original issue was in the surround. So would I use the nail polish as a glue to adhere the seam of the tear and then cover the whole spot with nail polish? This would likely require holding it in place until it sets too.

That's tough to see in the pics so here's what I suggest and you'll have to take it from there.

If you are doing repairs in the surround then use the rubber cement method. If you are clear of the surround and are working only on the cone and have good alignment of the damaged area, use the clear nail polish straight up, no thinner, no tissue. You still do the repairs on both sides of the cone.

Any specifics or preferences for nail polish?

Also, do you have any photos of repairs you have done? This might help me visualize the desired outcome.

Although I consider myself a modern day sensitive man I don't have a clue as to the nail polish. Here's how I acquire it: "Honey can I borrow some clear nail polish? I don't need much. Thanks Honey, I love you."

Photos? No. Just try it, you'll find you are an expert after just once, trust me, it's not hard. Just pretend they are you're children and you'll do fine. I like the idea of trying it on a spare driver first though.
