Hello Sandy - good to see you here. This forum is my sole on-line activity. My experience tracks yours. In all the years of demonstrating and exhibiting 3.5s, we (Thiel Audio) NEVER blew a driver, even when purposely tempting fate with high levels for extended time. But, news from the field mounted, we warranted many drivers, especially midranges with burned coils. The story was almost always moderately powered amps - 50 watts is enough to fry voice coils, but not enough to stay clean. Program material was almost always soundtracks or other oo-wow exhibition pieces. Rooms were usually large - required power rises as a cube function of size - it escalates very fast. And the "felons" often had compromised hearing - think rock concerts. A core liability of first order slops is vulnerability.
The first replacement driver was free under warranty, with a lesson and warning. If they blew another driver, the dealer had the option how to charge - we supplied the driver to the dealer at our cost. After that they were on their own. Under normal use with normal program material, a driver should last many years. But, "normal" has drifted to much higher demands than the old days.
