Hey Guys,
About a month ago I bought some RCF art300a's and i have some RCA>XLR, anyhoo.. When i touch these leads a verrry loud buzzing noise comes out of the speaker and it sounds like the cone pushes towards the outside?? or sumthing along the lines of that, they nare still completely fine but i was wondering how i could prevent this?

is it sounding like a earthing sound ? Have you tried another cable if you one have another...

Yup, sounds like an earthing problem.

Whilst I'm not a tech, here's an idea....

Snap the third (and bottom) pin from your 'jug-plug' IEC power-leads. This may remove the hum.

I'd try using a balanced audio connection to the speaker before you remove the ground.

removing ground is a bad idea......

do not remove the ground on your power cables.
the problem is either that the lead has some poor connection, the internals of the lead are not properly soldered or there is a bad join/ solder inside the box. provided of course this is happening when you brush the signal leads....
