KEF Ls50 driver issue!

Wow! that's sad....

If you zoom in on your very first picture, you'll see it. Whether it's a mark on the tweeter part or just something stuck to it I know not!

You’re right, it looks like a ‘nibble’ out of the extreme edge. In practice, it quite conceivable in a domestic setting that somebody has walked past with something perhaps long and pointy - a telescopic tube from a vacuum cleaner, and curtain rod, an umbrella, could be almost anything. It catches the edge of the tweeter, and dents the outer area on the way past, with barely a tap noise.

All supposition, but a theory at least.

Sorry, I thought I had covered the debris between the tweeters at 2 o'clock in a previous post. Updated image! 📸

After giving the KEF's a thorough dusting, I turned them on to observe how it affects the sound. The vocals are distorted.

I appreciate your perspective. I spent most of the night looking through various American sites and gathering information. These images, comprehend the appearance of a blown LS50 driver. The comparison is vastly different from my driver, which I'm putting down to a durability issue. The amplifier is not the culprit in this case.

Those examples are definitely overdriven - yours is more like physical damage. Abuse tends to be more uniform around the cone, particularly long term stress.

My money's still on accidental and unnoticed damage.

Not being funny, what hoover do you own ? Really looks like it was hit. Someone hoovering probably wouldn't realise they had struck the speaker.
