2x10 cabinet - best WGS speakers for hard rock

What are the best 10" speakers for thick, aggressive hard rock overdrive? I’m thinking Black Sabbath here. I’m used to hearing old English made Vintage 30s in a 4x12. I want to load my 2x10 cabinet with speakers from WGS and rock. Thanks!

open or closed back??

The 2x10 cabinet is convertible from closed, 1/3 open, or 2/3 open. With new speakers I would experiment to see what sounds best. I’m driving it with a Fender Prosonic head, 60W.

Gotcha! (cool, btw)

Sounds like the Retro 10’s in 1/3 open will be exactly what you are looking for.
