These aren't really results, just a crude view of the measurement in green and what it proposes to do about it in red. It seems to propose pretty flat response for your subs. The null around 200hz may not be critical but more about your room and speakers than the sub particularly. Finding best placement before running Audyssey is always a good way to go about it, and better yet get a measurement mic and use something like REW to see what's really going on.
