| Rockwoool, Owens Corning, Roxul, Thermafibre, OFI, Certainteed, are just some of the companies making suitable material. If your bass traps are 12" or more thicker, use regular "fluffy" insulation to fill them. If 6-12" thick, Roxul Safe n Sound or equivalent to fill it. under 6" use 703 up to 4" thick with a gap if over 4" thick.
