About a year ago I did an at-home comparison of the LFR660s* and the M80s and came to the conclusion that there wasn't enough of a performance boost to the LFRs to warrant the added expense and complexity. I think it may have been a set-up/placement issue and I wish I had spent more time playing around with placement.
(*I just noticed they no longer show the LFR660, anyone know what was behind that?)
I wonder why Axiom doesn't include a calibration chip and microphone with the DSP; similar to Audyssey or YPAO. Then they could tell you that you hit the proper band or you have to tweak more.
