Correct but you don’t need to daisy chain them. You could connect a non powered Kabinet to the speaker out and a second powered Kabinet to the Monitor Out or (if you want stereo) Direct Out with the Stereo Monitor box checked.
I would also add that if a single Kabinet isn’t loud enough for a rehearsal room, the problem isn’t that the Kabinet is too quiet but that the rest of the band are too loud. I say that as a 54 year old with some hearing loss and terrible tinnitus from too many years as a younger guy who though volume was cool.
Appreciate the reply. Wouldn't I need a powered kemper to do that? From what I've seen the power kabinets only have an input and no output
