Ok, that makes more sense. With this new information, I would leave your gain control where you had it as I seem to recall your levels were just about spot on before (+/- 3).
As a quick sanity check... the graphs vertical ("Y" axis) is the speakers loudness (higher up being louder). The graphs horizontal ("X" axis) is the frequency being sampled (left extreem is the lowest frequencies starting at 20Hz, the right extreem is the highest frequencies ending at around 20,000Hz or 20kHz). And trust me when I say... you are not the first to have issues reading these graphs
However, if you were misreading them when moving the speaker around using Quick Measure... than everything you thought you learned while using Quick Measure is probably of little use
I would recommend that you run Quick Measure again and see what you can learn now, with this new info, as you move your sub around.
As for simply setting the Target to 120, this may gain you a very small amount, if ARC is able to apply some boost where the sub is starting to roll off... but in reality it is unlikely to accomplish much. Simply changin the target number is a bit like taking a car that can do 80mph with a speedometer that goes to 80 and replacing it with a speedometer that go to 120 and hoping your car will now go faster. Just cause you raised the numbers doesn't mean that your speaker will magicaly be able to perfom better. Remember, ARC is setting the cutoffs where it find they should naturaly be after testing
As an interesting experiment, run Quick Measure... and without moving your speaker, simply turn the crossover control down, look at the graph, than turn the crossover control up and look at the graph. You should be able to see that the graph will get narrower as you set the crossover control lower (the right hand side of the graph should move left while the left hand side should not move). As you turn the crossover control up, the graph should get wider (the right hand sided of the graph should move to the right, again the left hand side should not move). Of course allow a few sweeps, at each new adjustment you make, so you can see the change. Obviously our end goal is to get the right hand side of the graph to go as far to the right as possible, hence setting the crossover control as high as it will go (180Hz or as far clockwise as the knob will turn, I have a feeling that 180 may be the largest number displayed on the control but that the control will actually turn a bit further to more like 200Hz).
