The Shocker Super Extreme coils I have are only really suited to 800W continuous, though possibly not so much. The ones I've sold to guys on here have a different TC coil which holds a bit more power.
Copper is best for music since it's heavier and is better for continuous power handling. Soft suspension is your friend. Pierce Audio has a decent medium stiff spider, a single one of those would be good. I have used softer ones in the past, but don't have access to them anymore as all I've had were new old stock from a company that's gone the way of the dodo bird.
Exotic baskets are nice, but expensive and 10" spiders are about 2 or 3 times the cost of 8" spiders and harder to find.
I have a couple nice 10" cones here. Some 10" cones you'll find sit too deep on a standard basket to mate nicely with the top landing so you need either a special basket or 7.25" spider to sit on the next lower landing... or just be aware that you get a 10" cone that mates to the right landing for you.
I haven't built any 10's with the TC9 motor yet so I can't really comment much on what combinations get what specs, but it's a really good platform and the 12's and 15's I've made model fairly well sealed. IMO TC9 is one of the best all-around motors out there.
