A method for manufacturing a loudspeaker includes creating a dual-layered fabric having an acoustic resistance by attaching a first fabric having a first acoustic resistance to a second fabric having a second acoustic resistance lower than the first acoustic resistance. The method further includes applying a coating material to a first portion of the dual-layered fabric. The coating material forms a pattern on the first portion of the dual-layered fabric that changes the acoustic resistance of the dual-layered fabric along at least one of: a length and radius of the dual-layered fabric.
