I actually checked the LFR1100 product page and they have added the fact that both arrays are nom 4 ohm. I'm just annoyed about the lack of information on Axiom's website. These are their flagship speakers and no owner's manual, probably a wrong weight spec, v3 pictures etc. I'm the who asked if the DSP doesn't have a 12v triigger, why are you advertising that it does? They changed it at least.
