True that, yeah. It could totally work, I think. So, everything stays on/plugged-in, and then you just program/set your smart-switch to turn on when you want it to. Something like one of these would do the job just fine, I think. And 10A should be way more than enough for your active speakers. They all come with apps, as far as I know. I've got a couple of them that I set up on my lamps/string lights throughout my apartment. The one I linked specifically mentions being able to set "schedules" so I assume that means it's programmable to the hour/day. But yeah, they're all pretty similar, from what I've seen.
