DC out speaker calbe
Hey everyone,
I’ve got DC coming out of my speaker cable on my Luxman C120A and C120M, which sometimes pushes the woofer cone of my Elipson 1303D dangerously forward, along with some pretty nasty noises. Just to clarify, the issue is not coming from the Elipsons—they’ve been refoamed and properly centered.
I’ve already done a full recap of both the preamp and the amp. For personal reasons, I don’t want to take them in for repair again. Instead, I’d prefer to fix the issue downstream and protect the speakers.
I’m thinking of building a small box inline with the speaker cable, using two 4700µF 50V capacitors back-to-back at the input, along with the LJM speaker protection module (shown in the photo above).
Does anyone have experience with this kind of setup? Any advice or pro tips for this type of DIY solution?
Thanks in advance for your help!
