One says more FRFR than the other says less FRFR than... The joy of gear eh! 😀
FWIW I love a 212 cab- mine is quick and responsive and seems to enjoy getting fed more watts. It just feels like it can keep going and while my single 8ohm 112 is a capable one box solution a 212 really stands out as being bigger and better. Just something great about 212’s. Have you pulled the trigger or still deliberating? I don’t think the few kG’s lighter would sway me to change but I’m sure they’re decent cabs. Probably a fuller sound in the non slim configuration but vim only basing that on my 212M compared to its 212S counterpart.
