I'm gonna be using these legs from amazon on my next project. You can get them custom made to any size and come in different thickness/widths.

Funny. My sub is in the back right corner of the room. I'm hoping this isn't a Tyler Durden scenario.
The desk sounds nice.
Maybe could find legs with more steel that don't need a weld? https://www.amazon.com/gp/product/B07C6KNTR8/ Alternatively could find a metal plank, but that could be some funky sound without some kind of base insulation that raises height more.
In any way am interested if you can find something here as I need some ideas to avoid ending up with a soundbar.
