If you're okay with the tv height, then no need to change. But you can get something like this
It's adjustable so you can clear the space between the bottom of your tv and the area on the top shelf to place the center speaker. It also looks cleaner, with the looks of a wall mount. This really helps with clarity of the dialogue and front soundstage as they're closer to height of the left and right speakers when you get them off the ground.
Only solution I see is elevating your TV, either by wall mount or table mount. Could also find some very short speaker stands maybe, but that'd look silly.
Also, pictures would help with ideas.
Speakers behind the TV cabinet may cause bad reflection with the TV in front.
You could get a stand clear up some space under the TV. VIVO Black TV Table Top Stand
