Abstract
A grille cloth for speaker assemblies is preformed into a desired shape and has sufficient rigidity to maintain this pre-formed shape while being supported in a non-tensional manner only at its periphery. The use of such a pre-formed fabric as a grille cloth eliminates a need for non-peripheral support while visually obscuring the components of the speaker assembly behind the grille cloth. The grille cloth is comprised of a polyester material which is substantially transparent to acoustic radiation in the audible frequency range while also being substantially opaque to visible light.
