Hissing from Martin Logans Arias i's


I am noticing a constant low hiss from the speakers with power on. Nothing else is powered up but the speakers. Anyone else experience this and how do you get rid of it? Thanks...

Probably around $4-500. The panels should last many years. If the volume starts to fade in one or both, that is the time for panels, not before.
Thanks for the reponses. I broke out the vac and it significantlly decreased the hiss. I only hear it if I put my ear right next to the panel. Thanks all...OBTW anybody know the cost to replace the panels?
They probably need vacuumed. Carefully vacuum the panels. Martin-Logan recommends doing this 2-3 times a year. My SL3's were hissing and vacuuming resolved it. Hope this helps.
I'd check for dust accumulation. Try powering down the speakers for a couple of hours and then carefully vacuum both front and back stator panels. You can contact M-L as they are very helpful with recommendations. Good luck.
your interconnects are picking up rfi,shielded interconnects will fix the problem.
