Since the MiniDelta uses a non-standard barrel plug, I pieced these two connectors together for an adapter.

Mind telling us the brand and model of these speakers?
Mount them in a wall that is not finished on the other side?
One can run 12v power over the same CL2 cable that would be legal in-wall as speaker-cable, and barrel-plug terminals are available in most sizes that make such extensions easy. You still need an accessible spot to transition from in-wall cable to the plug-in power-adapter cable -- which has to be outside of the wall and ceiling.
My preference would be one of the bluetooth amplifiers that mounts in a standard single-gang wall-box, and passive-speakers. This also gives you a volume knob that might normally be never touched but is convenient when you are on a phone call and someone else in the family is trying to play COD on the computer upstairs and not working out why they aren't hearing anything, upstairs.
I'd also not put them in the ceiling if soundproofing to/from upstairs is at all a concern.
