I have known the B&W brand for years , the inspect and pack each speaker in their
top range which your speakers are ,anyone with half a brain 🧠 brain would inspect the polished head and see this defect , this should have been rejected at the plant and repainted. No driver ever should have went in there , this is a disgrace .
I would send these literally 3-4 emails to B&W U.K ,as well as the distributor
how long has this been ? You needto act on these NOW.
how did you pay for these and how long ago ? Never put anything on layaway ,why you loose the 90. Day claims with credit card companies . We cant help you if you don’t explain these could be fakes also , I have never seen this condition ever in any stores or homes .
