I still don't understand why Troy has this problem with M80s. The problem with on-walls is zero soundstage depth. I've moved the back of my 80v2 three feet from the front wall and I've been stunned with the improvement in depth. I want more though.
As for the LFR, the listening window and sound power responses are textbook! What an amazing journey Ian, to come from a time when you had to use pen and paper, passive components and loads of manual characterization just to deal with what are now mundane challenges to optimizing characteristics that were once the stuff of dreams.
