Speaker grilles

Recommended Posts

I have been looking into what type of grilles to fit onto my homemade cabs, when...

I noticed that some grille cloths are advertised as 'acoustically transparent'.
This led me to wonder how much a punched steel grille affects the sound of the average bass cab?
Some steel grilles are listed as being 40% free air, so this must have an affect.

I did some tests on punched metal grilles and found that they caused a a very slight reduction in HF. They won't affect bass guitar frequencies at all, although it makes sense to go for the more open ones. A wooden frame and cloth grille is lighter than a full punched steel type.

That's what my ears were telling me, I just wondered if I was imagining it!

I bought some of this [url="http://www.bluearan.co.uk/index.php?id=ADH0721&browsemode=category"]http://www.bluearan.co.uk/index.php?id=ADH...semode=category[/url] to use as a temporary measure, but it looks awful as I cant get it to sit flat.
I was thinking of ironing it under a damp towel.
Has anyone had any success with it?

I haven't decided whether to go for metal grilles or cloth.
If I go with cloth, would a piece of 6mm ply with the speaker and port holes cut out of it do the job as a supporting frame?
(I have searched the net and can't find much info on making grilles).

I haven't used that particular cloth, but heating with a hairdryer usually tightens up a cloth grille. You could try a frame made out of softwood batten, say half or three-quarter inch inch.

Sorry, no use I know...[/quote]

Actually, your reply is a lot of use, thanks.
It will save me lots of time.... and thinking I am missing a trick on how to fit it nicely.

I'll chuck it in the bin!
