Play, your picture isn't showing up anymore, could you post all your settings again? Just got my M3LR and the sub is awful and I hate the front sound stage, just sounds so weak.
I'm a metal and electronic guy, so I tend to prefer a V shaped sound profile as well. Currently, based on your description, I set mine to 4, 2, -4, -3.5, -2.5 to be what a v-shaped curve is, but to counteract the lack of bass.
