Those are the AdaptiQ speakers that are essentially a in-wall version of a jewel cube speaker....they are a goofy low impedance and sound like crap with a traditional AVR. I really have never seen them used as DA speakers and the certainly have never been marketed that way. They are designed to be used by the TA-2 or TA-3 surround amplifier
This seems contradictory to what I've found. The amps are rated at 6ohm minimum and there's only a single pair of speakers connected to each amp so they have to be at least 6 ohm.
The amps are SA-2 & SA-3 which seem to be designed for DA systems and are setup with optional in-wall volume controls which are resistance based. The only room with surround has a totally different amp (TA-2) which does appear to be designed for home theater with LCR, surround & sub outs.
