I have a receiver that weighs about 15lbs on the middle shelf and other units that are less. In total, I have about
7-8 pieces of A/V equipment on the shelves that's close to 100lbs. The shelves are very thick and would support just about anything. I would
not eliminate the center dividers because, although they could support the weight, the shelves might "SAG" and "BOW" over time.
