I'm guessing you don't open the drawer below the TV. Maybe a speaker stand made out of 2x4's would work. Just make the base and top the same width the center speaker. Make the center part just high enough to place the speaker and the top in front of the TV without blocking the view. Might work.
Or figure out the measurements you want and try to look for a stand on Amazon. Might find one there.
You could put the TV on a stand like this: https://www.amazon.com/gp/product/B00KKHUPPS/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&th=1
