What Could Cause Center Image To Present Lower than Expected

Having the speakers 4” from the front wall is doing you no favors, especially with excellent speakers like yours that image/soundstage so well.  The first thing I’d do is pull the speakers out at least a foot , and two feet even better, just to see what happens (don’t worry about how it looks for now as this is just for experimental purposes at this point).  Also, I’d try the speakers more like 6’ apart and experiment with toe-in — I like angling my speakers, which are similar to yours BTW, so they fire just outside my shoulders.  I bet just doing these few things will make pretty significant improvements all around but especially in 3D imaging/soundstage.  Also, if your listening chair is against the back wall pull it out a few inches, and your ears should be at tweeter level so if your seating height is above the tweeters that’d be something else to adjust if possible.  This is just a rough starting point but would be very interested in what you find.

+1, in addition, I’d put some damping on the first reflection point on the side walls

I think the totems like to be ~4 feet out from the wall.  You can also move them a little closer together as Soix suggested, but  I’m not sure if the-in will be good, not that close together. Totem recommends no toe-in.

Maybe try blankets and pillows on floor to lesson low reflections. If that works then replace with a rug with a thick pad.

Room tuning or speaker repositioning would help but I would suggest a different approach to try first. Swap cabling, both interconnects and power cables (if not the same). Most likely is the TV screen behind the speakers and any other big reflective area between them. Sometimes a cable swap can alter things.
