I have seen many posts on many forums suggesting acoustical friendly fabrics to cover traps and while I can understand this for general absorption of the higher frequencies, I cannot understand why it is often also recommended for bass traps. When trying to trap the lower frequencies, people often use FRK covered fiberglass which is going to reflect the higher frequencies so why not just recommend pretty much any fabric. I would think the lower frequencies would go through pretty much any fabric and if the higher frequencies are reflected, it's what the FRK would do in any case. :scratch:
Thanks in advance for any explanation.
