quick context: i received a free non-functional tiny combo amp with an electrical issue and a slashed/nasty grille cloth. i fixed the amp issue and removed the nasty grille cloth...what do i replace the grill cloth with? so...is there any cheap (free) substitute for grill cloth? the area to be covered is tiny, about one squre foot. would a t-shirt work? paper towels? mosquito screen? all items i have on hand atm ... or does anyone here have a better idea? i sure hope so ...
Just grab a pair of plus-size pantyhose, slide 'em over the frame, and trim off the legs. No logo but you'll have a pretty spectacular cotton crotch panel. Riis
Another stupid idea but I have a stock roll on hand: interweave lawn chair webbing and staple on the back. It's that ungodly green which just screams "rock & roll". Riis
available at home depot .... enough to make several grills. 36 in. x 84 in. Charcoal Polyester Pet Resistant Screen Roll for Windows and Door
this sounds great! and yes, i'm looking for something i have on hand ... don't have any of that stuff, though.
Black polyester interfacing fabric from a fabric shop is really cheap and fairly acoustically transparent; limiting the choice to what you have on hand, I would go with the mosquito screen. However, I voted for you to bite the bullet and buy some actual grill cloth fabric.
Woven polyester (doubleknit usually) is the practical alternative that a lot of folks use. The thing you're trying to avoid is acoustical resistance - that arises from forcing air through small holes, so the cloth with the biggest holes between fibers is what you want. Polyester also stretches enough and doesn't warp or shrink over time - you can stretch it a bit on a frame, and over time it'll stay there.
I have actually used this on a cab back in the 70s ... it lets the sound out and it protects the speaker
fabric store is a good idea... lots of different materials designs and colors for cheap. I like the tie-dyed t-shirt idea,depending on amp width
Go into the fabric store. Browse around. One yard of pretty much anything will be more than plenty. By the one that makes you grin the widest. Could be your favorite football team (or soccer, baseball, basketball, whatever). Could be My Little Pony. You do you.
