I got a chance today run some more sweeps. The results are as follows.
These first two below are on the sub only with just the AVS internal filter smoothing the 35- 50hz rise.
The first graph is the raw result.

And this graph is with 1\3 octave filter applied

This graph is with the mains running and a room curve applied as well.

And the same with 1/3 octave smoothing

And finally a full range sweep with 1/3 octave filter applied.

I'll still do some tweaking and fine tuning and see if I can smooth out the mains a bit, but i'm happy with the results over all, the sub has good response to 13hz.

I haven't bothered to try blocking one of the ports on the sub to raise the bottom end, it seems fine to me how it is now with the room gain. I might give it a try some day when I have some free time.
I haven't had a chance to demo much listening material out yet, but what i have listenend to sounds very nice. There is no boom and the bass is nice and tight.
I'll try and watch a Blu Ray tonight and give the set up a good work out.
Thanks again brucek for your valued input.
