I’m looking into building an A/V cabinet. A couple of sections 18 in wide for equipment, and a third section I’d like to put in my older sub mounted downward firing (and out of view behind sliding shelf doors). Overall ~5 1/2 feet wide, a 20 in. shelf height box supported by the sides to the floor ~ 28 in. overall height. It’s got to meet ~WAF standards, as it will be in the living room.
Thinking a nice finished solid wood top, and looking into ‘pouring’ a couple of concrete sidepieces (rough cal of 28x18x1.5 inches each side will weigh in around 60 lbs, so the sub should be stable).
So I’ve been looking at YouTube diy concrete tabletops, and thought I’d check in with the builders here. Has anyone given the concrete tabletop a go? Any ‘learned’ advice?
