Have any of you ever built a speaker and used grill cloth so thick you cant see through it w/o a flashlight ?
My friend just built some speakers, and he has the drivers hidden behind some really thick stuff, and covering the port as well!
Can this effect port tuning too ?
What might be a better grill cloth material to use ?
What, if anything, will relatively thick grille cloth do to sound/port tuning ?

There may be a published absorption coefficient or sabins figure for the material. If so, using that and its position, you can predict what effect it will have. You could also use something like Speaker Workshop to measure the speaker with the grille on and off, and compare the difference.

I've settled on thin silk. About $12/yard. If you are artistic you can use water colors to add a fashon statement. If not, buy pre-dyed.

I build two curved aluminum rods, left/right, sew a loop on the end of the slik that slides onto the rods, and tenson the silk by pushing the ends of the Al rod into holes on the front baffle. Looks a little like the Revels.
