With proper care & no abuse the 802Ns might outlast you.
speaker maintenance
I own a pair of B&W 802N's that are almost 8 years old. I maintain the cabinet's with fine wood polish, and they still look brand new. But what about the drivers and posts. Is their anything I can be doing to prolong their life and keep them up sonicly? How long should I expect them put out at their maxium potential?
