fiberglass multi-pattern actually helps bring all frequencies out and expand them...the pattern I created here actually de-accelerates the sound waves into a very spacious sound "meshing" unlike fabric which has a deadening narrowing...this mesh material tunes the sound waves and it comes alive due to their fractal nature- and allows pinpoint accuracy and a wider stage fooling the waves into a creating a larger than life pattern while minimizing any echo or ring in sound waves - it works better than fabric (the idea comes from using much more expensive porous/foamed aluminum similar to ones used on the back wave of the Abyss AB 1266 TC or the Meta Material used in front of the Dan Clark Stealth or the Meta material used in the KEF speakers)
