I think my subwoofer placement is horrible. I might have to make some room on the left side of the room.
X-Curve is based upon psycho-acoustic analysis and large room environments. I would suggest that you try -2 to start, then play with a range -.5 to -3.5 I will bet you end up near -1 to -1.5 at most. (Actually what speakers do you have and are they toed in or straight?)
Here is a non-complex article discussing its origins:http://www.micasamm.com/publications/surround_0100b.htm
This one actually gives a very clean perspective:http://www.hometheaterhifi.com/volum...es-6-2002.html
Use a test source - after each adjustment - with LOTS of HIGH FREQUENCIES since the X-curve was implemented with those in mind. An opera with Arias, music with lots of high hat/cymbals (good jazz trios work nicely). Even a little Maria Carey might work. Let the SC warm up for 30 minutes on some other netral piece before each listening session. You should listen to a mix of tracks over a 10-15 minute listening period and repeat that same sequence twice for each adjustment before adjusting again. Treat it like a MCACC calibration, quiet, just you and no other presence in the room and your favorite position in the room with speakers in their final positions.
Now for some unsolicited room layout advice:
1) I would recommend moving the sub to the left (seems it is in the right front by the doorway right now?). I would move it front of or behind your left front speaker (I can't tell what's already there) and re-running MCACC first before you adjust the X-Curve. When you do step 2 you will have plenty of room. Given the size of your room some addtional bass reinforcement could not hurt.
2) I would move the entertainment center over to the right to match the middle of the couch and the room - almost. Then you can move that Right Speaker over (Right) for better imaging. Alternatively I would move the couch a bit to the left to improve imaging off axis.
3) Buy 2.0 speakers for your system for the SBR/SBL. Your room with that 7-8 feet behind the couch is PERFECT for a 7.1 system. Consider two more speakers and you will be in surround heaven. If you have unipole for your surround side you could move those to the back, set up a THX ASA speaker array (separated by less than 4 feet), and purchase maching dipoles for the sides. Then you would be just amazed. Alternatively two more unipoles in back would do wonders also...
Oh what fun...
