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
