Yes. The transition from your subs to your main speakers as the frequency goes up will no longer be seamless.
However, that aside, if you raise the subwoofer speaker calibration level after Uploading ARC results you will indeed end up with hotter subs if that's what you want. You could also raise the subwoofer's internal volume control after doing your ARC measurements.
But my recommendation would be that you should live with the results ARC has produced for quite some time before second guessing it.
Another thing to think about is whether you actually have enough subwoofer for the total air volume you are trying to pressurize in your listening room, and whether your subwoofer polarity/phase settings are correct. Often the feeling that the sub volume needs to be increased, despite calibration readings, is due to one of three things: (1) You have serious uncorrected cancellation nulls at various critical frequencies in your listening room such as around 50-60Hz. ARC should deal with that. Or (2), you don't have the Polarity and Phase adjusted properly for your subwoofer so you are getting cancellation near the crossover frequency when audio from the sub and from your main speakers cancel each other out because they are out of phase with each other. Or (3), your subwoofer is too small for the air volume you need to pressurize. Often, calibration readings shows proper sub volume but you don't have the "gut feel" of enough bass. In fact this also means you are likely stressing your sub by making it work so hard.
Check the subwoofer forum here for advice on how much subwoofer you need for a given listening room volume. The Velodyne site also has a sub selection dialog which will give you some idea based on their models. Adding a second subwoofer is sometimes easier than upping the size of a single subwoofer.
