Audyssey Setup Question

Today I did another Audyssey setup and noticed a significant improvement in the subwoofer response. The subwoofer is a Martin Logan Dynamo 700 and it's hooked up such that it should bypass any internal cross over. This morning I was playing a CD with heavy low bass and noted an obvious transition into the subwoofer when the bass dropped into its range. After doing the setup it was nearly seamless. I did set the subwoofer cross over as high as possible this time, but it shouldn't matter from what I've read in the manual. The only thing that I did differently was to do five measurements rather than the normal three with the last two being between the first three. Should that make a significant difference or is something else going on?

This is the first time with the subwoofer setup in the forward firing configuration,but I don't see how that would make a significant difference other than it doesn't put so much vibration into the floor.

Any thoughts?
Flattening room response is one of the goals of Audyssey room correction and it sounds as though it is very beneficial in your listening room. Many audiophiles are either lukewarm or opposed to room correction, but it serves to allow more realistic reproduction of music in the real world.
Generally, the more room positions you sample, the better the integration and correction of the bass will be.

The other possibility is that - in the first instance - you were crossing over low enough such that the bass content in the music was sufficient to drive your main speakers into less than ideal performance. Once you directed more energy away from the main speaker and to the sub, instead, the monitor began to "behave" better and the whole system sounded better (and better integrated).

Just another idea.

I found the more measurements the better, I did 7
