I just recently got my hands on a pair of Onkyo SC-670 floor speakers. I got them for free since the woofer and the midrange speakers are broken. I've looked at a few replacement speaker for the woofers and midrange speakers but I'm not sure if they're the right ones for this enclosure. For the woofers I've chosen the Dayton Audio RS-225 4 Ohm and for the mid range I've chosen the Dayton Audio CF-120 4 Ohm. The tweeters still look fine to me so I don't think I have to replace them. I haven't ordered them yet since I'm not sure if they would be the right replacement for the original speakers since I don't really know much about all of this. I've provided some pictures of the original speakers below.

You could try to just exchange the surrounds (if that is the only problem!), that would be much cheaper and does not need adapting the crossover.
Just some google search results:

That does sound like a great and cheap idea and the previous owner said that that was the only problem. I'm not very confident in my fixing skills though 😅

For reference, here are the specifications of the Onkyo SC-670: https://audio-database.com/ONKYO/speaker/sc-670-e.html
And here, a German supplier of a complete surround replacement kit (2 x bass driver surround and 2 x midrange driver surround):

Pricey perhaps, but at least you'd be sure the surrounds would fit.
