Woofer recommendation

Hi

Happy new year to you all 🙂

For my next project/experiment I was thinking about using my B&C DE250 as tweeter and combine it with an high efficient woofer and some kind of subwoofer.
I was thinking about something like an 10" or 12". Recommended cross over for the DE250 is 1600hz, so I must at least go as high as that.
I am also considering if I would be better of with a 8"?
I am open for suggestions...
Any drivers you can recommend that sounds good?

It will be an active speaker using my Hypex FA123 modules.
