I just a bought a Stanmore II from a 3rd party personal reseller
Yes I'm aware there are inherentl risks concerning quality with transactions like this. I'm also assuming the speaker's outside of any warranty period but that's moot considering I didn't buy it from Marshall or an authorized retailer.
So the problem is The audio quality. The audio is muddy. It's muffled. I've done everything suggested in the manual and online including updating firmware and adjusting various source/equalizer and audio levels.
Because there s some light cosmetic damage (scratches) on the front of the speaker, I'm assuming it was dropped or damaged right on the cone of the woofer. My question - if my assumption is correct should I open the speaker up and visually inspect it for obvious signs of damage? Could dust or water have caused this and would that also be obvious?
Is this a good question?
You might want to open it up and take a closer look. Start by inspecting the speakers for any visible damage, and then check the circuit board carefully. Pay particular attention to the soldering on the speaker connections—since you mentioned a possible drop, it’s quite possible that a joint has cracked or loosened. Even a small break in the solder can interrupt the signal, so reflowing or reinforcing those connections could resolve the issue.
