The learning curve is only steep at first....I hope, I get such little time to do setup, here's the problem I'm having, I'm getting readings down into 20hz and above with my klipsch rf-7's, I'm in stereo mode, all speakers set to small, crossover set at 80hz, sms-1 crossover off. Sub set for lfe output. Just to make sure it wasn't my sub, I shut it off, it's my rf-7's that don't seem to be responding to the 80hz cutoff. Shouldn't the graph be starting around 80hz like in the manual?
