I suspect in your case you just had the old sub way louder than the SVS.
Second explanation could be that the current location of the SVS is not optimal and there may be nulls or dips which is robbing the performance.
My other concern is that when I ran Audessy (sp?) on the old, it put the sub at -12db.
This simply just meant that you had your old sub's volume knob very high (perhaps too high). Remember, the higher the volume knob on your sub, the lower the trim set by Audyssey.
The SVS came in at -6db.
Following on from what I wrote above, this is simply because the volume knob on the SVS wasn't turned up as high. If you crank up the volume knob, Audyssey could set the trim at -12dB for the SVS (like with your old sub).
I keep hearing (reading) about how the SVS plays at a Flat frequency response. Can someone put that into laymans terms?
This means that the SVS was designed to reproduce the bass frequencies (within its range) at an even level, e.g. it would play 25Hz or 30Hz or 40Hz or 50Hz all at the same level. If you looked at the graph it would look pretty flat, as shown below:
