Dings on B&W 802 tweeters

Any 'dings' are harmful to any exotic audio equipment. If they sound okay then it is 'okay'. Regarding repairing the damage is another story on its own. Did you try to contact B&W UK about this?

Kind regards,

For what it's worth, I have B&W CDM 7 NTs -- plainly a different speaker with a different tweeter from the 802s, but somewhat similar design from the same manufacturer. I inadvertently damaged the tweeter on one speaker -- a substantial ding, with a pushed-in mesh covering. As far as I could tell, there was no difference in the sound. But I disliked how it looked, and had it repaired i.e., the damaged parts replaced with new ones -- for a reasonable sum by a local dealer. No doubt you could have the 802 repaired as well.

A few years ago, I purchased a pair of used M803's that had the tweeter pushed in during shipping. I was able to purchse a new tweeter (the guts) for around $120 from a dealer. Very easy to replace, especially since B&W did not solder their wires but instead used push on connectors, at least on the M803 tweeter. Regarding repair, do a search on this forum and audioasylum as this has been posted many times. In brief, you can try various things to make the dent go away, but will probably never fully "repair" the tweeter to like new condition. OTOH, you may never actually hear the difference. Play some tunes with clear high frequencies on mono and compare between the "damaged" speaker and the "undamaged" one, to see if a repair or replacement is needed.
