B&W Nautilus Tweeter blown adhesive failure design fault
My tweeters failed on my N802. After examining them carefully I discovered that the foam surround is stuck onto its plastic mounting, and the adhesive had failed which allowed the voice coil to come out the gaps and overheat as it was not being cooled by the ferro fluid. The replacement tweeters are modified so that the foam surround is bigger and is trapped under the outer tweeter housing so is not relying on the adhesive alone. To be fair on B&W, the speakers are about 15 years old, as I bought them used from a guy on ebay about 2 years after they were launched. B&W gave me a refund for the parts after I explained my case. The only other company with such a great service and commitment is Meridian and its a fine attitude such as this that makes me a life long fan of their products and will keep me buying their products for years to come. Well done B&W. ;x(
The new tweeter is on the right, the blown one on the left. Note how the foam surround is larger on the right.
