I'm trying to figure out the best way to install some bass traps. I'm thinking about putting them on the floor, but alternately suspending them from the ceiling but leaving the tops open. Has anyone tried this and then tested in REW? I'm trying to there's any alternate materials or sources for the tube design for the fiberglass that's meant to insulate pipes. I'm looking at this (https://www.jm.com/en/mechanical/pipe-insulation/) but its almost $90.00 a unit in the Toronto area. I'm trying to come up with a more budget DIY alternative if anyone got a suggestion
