Audio racks that can handle heavy components

100 lbs is nothing. my amp weighs 300 lbs. I have it on the top of a rack I designed myself of welded 1"x1" x1/8" tube steel. 6.5’ span with zero sag.

I will give you an idea. I laid out my equipment and measured how long and high each shelf needs to be. I had it welded up at a local weld shop for $300. I included a 1/4x1/4" steel bar on the inside bottom of each tube to hold the shelves. Instead of solid shelves, I cut 20 1" x 3" boards and stained them ebony. I spray painted the rack black. I velcro’s foamboard on the back of the rack and cut holes for each cable behind each component so all the cables are hidden. The rack pretty much disappears around my equipment. anyway, cost effective way to make a nice looking custom rack that will hold anything you want.

I bought a used stack in MAPLE including two side stands for speakers from a guy for about 40% new pricing. Found another stack I picked up out of state en route to our new home for even less.

Sturdy, solid, great woodgrain. Comes in Cherry, Walnut and Black also but at a cost.
