But from RCA to XLR, you need something to generate the inverted signal--thus the active device.
The current manual says: "Your subwoofer is shipped with a supplied 1/4” Phone-to-RCA-jack adapter already installed in the XLR female input. Connect a shielded coaxial cable, with male RCA plugs on each end, from the A/V receiver or A/V preamp processor’s Subwoofer Output jack to the RCA female jack on the 1/4” Phone-to-RCA adapter."
If an active device is needed, how can Axiom do it with an adapter? Or maybe they're not referring to a physically separate adapter here ...
