Please re-scale your graph for a 15-200 Hz horizontal and 45-105 dB vertical axis. You can do that by clicking on the "Graph Limits" icon in the upper right corner.
Any equalizing comes at the expense of headroom. Whether or not you have enough left - you'll find that out once you start using the system. The tell-tale sign will be nasty noises from the sub drivers as they bottom out; however, some powered subs have built-in limiters to prevent this. In that case, you'll notice that bass levels no longer increase in volume with the rest of the system.Should I apply a house curve? Is my boosting okay, given the graphs to show the result? Both amps are at only 1/2 volume, so headroom should be okay?
