I’m building an entertainment center. Just below the top, I’ll have a large area where the sound bar will fit. It will be 60” long and 20” deep. Then below that are the shelves and drawers. I’m planning on building the top piece from 5/4 ash. The rest of the piece is ash and ash plywood as well. The top will only be supported on the edges. I’m trying to avoid any type of center support.

According to the sagulator, this should work. There won’t be any heavy items on the top. Maybe just small decorative items. Does anyone have experience with a build similar to this?
