Heres the correspondance
I dont think a Celestion F12-X200 200W FRFR speaker (
https://celestion.com/product/f12-x200/) is going to be overpowered by a 180w amp (Redsound specs) if the impedance of the speaker is the same as the Redsound Elis 8 passive cab (which is what I asked)

What they said makes sense to me. There's more to it than impedance matching.
You can't adjust the left/right balance of the speaker pair on the powered cab, so if the speaker's efficiency is different one speaker will be louder than the other. It'll be up to you to manage that inside the preset.
The speakers they use are a coaxial 8" and 1" pair and are matched to work together with their passive cab, and they do that
extremely well. A 12" speaker will definitely have a lot more lows, and again, balancing the EQ and low and high cuts for the sound would need to be done inside the preset.
The OUT, PEQ and GEQ blocks, or the CAB block would be where I'd tweak and then store the block in the library.
If I remember right, the power amp is 180 watts
per side. That shouldn't cause problems power-wise for the Celestion, but combined with possible differences in the efficiency with the powered cab, you might find one side doesn't get as loud, so you'll have to adjust the balance and could get some clipping if you really push the system. I guess trying it will reveal any problems, or it might work just like you want.
I think they gave you good advice. You can do with it what you want.
