metal grill material for amp cabinet

timsch75 · 11th July 2006, 03:41 AM

I put together a 2-12 cabinet and want to put a metal grill on it. I have a 1/4" diamond-hex pattern in mind. I've searched, but am only coming up with cloth recommendations. Granted, I don't want the sound to be noticably affected by the grill, but this is not an audiophile application and I want some heavier-duty protection for the drivers. Does anyone know where to get some material for this? thanks

Is this the kind of thing you're after? http://www.nextag.com/RAXXESS-RSG15-...72/prices-html

That is the diamond hex pattern, but I'm looking for a finer material and one with less mass per area. There is so much material on those that I'm concerned about the affect on the sound. I can only think that alot of the sound will be reflected from those grills back onto the drivers and would muddy the sound. I actually have something almose exactly like that on a subwoofer, but decided against them for this application.

I should have been more descriptive in my initial post. I'm really looking for a place to get some bulk material that I can cut a rectangular piece from to cover the whole cabinet face.

Google "perforated metal" or "wire cloth" or "wire mesh"

Actually, what you are looking for is called "expanded metal," so google that. That is where a sheet of metal has little cuts made in it and then the sides are pulled apart resulting in those diamond shaped openings you want.

Your local welding shop or possibly a sheet metal shop should be able to help. For that matter Home Depot might. CErtainly one of those screen door protectors could be adapted.

Look under "steel" in the Yellow Pages; you might have to buy an entire sheet if you get it from a wholesaler. Or try hardware stores; they often sell "hobby-sized" pieces of steel (at a large markup).

For cutting it, I used a cutoff disk in a Skilsaw, but a reciprocating saw or sabre saw with a good metal-cutting blade should work (without the nifty shower of sparks, though).
