Take a good look at the dirty great crease running across the cone.

Fit only for the bin yet being flogged by a so called "credible" dealer.

Looked like something has knocked against it.

The sticker on the magnet in the 4th photo sums up the condition:

Pmsl nice one wonder if both drivers are like this?

It's been a lot of years since I had credos but is that the original soldered wire?

 

[colasblue]

Don't think so. All Naim speakers I've owned have the same, very inflexible black & red wiring on all drivers. It's a real PITA to correctly dress on any of the models with sprung tweeters.

My concern would be the concentricity of the voice coil with the magnet.............

 

[colasblue]

That will definitely be off and coil former will rub against the pole piece in consequence due to the insanely tight gap Naim used. What will also be off is that you will be able to find some note or dis-chord which makes the driver "fart" appallingly. In my experience as soon as they get a crease they are done, and you often see them with circular creases where the driver has been blown "inside out" by the power amp.

good point when I changed drivers on SBLs the wire was thick and heavy not like the photo
