Looking at your pics I can see some obvious problems.
1st, your center speaker is way too low, it's pointed at the feet of the 1st row so most of the sound is not reaching the rest of your seating. That speaker should be located at about the middle of your screen.
2nd, move the media rack that is blocking your right speaker.
3rd, research the set-up of multiple subs and I believe you will find that, typically, you want to place them in opposite corners. It appears as though you have both in the front of the room. Plus, it looks like they may actually be interfering with the sound from your main speakers. Try to not put anything in front of your main speakers.
4th, your mains are rear ported speakers and it looks like they could use more space behind & to the sides. Try moving them out from the front wall and away from the side walls and see if that helps.
Try these tips and see if they improve your "wow".
