I'm not sure about Eminence's ratings, but I do know that the LAB12 driver fails with 375 watts continuous power input after an hour. The failure mode is thermal; The voice coil glue fails and the wire unwinds. This is pretty close to 400WRMS and few people run drivers this hard, so their power rating seems pretty close to me. The driver's thermal capacity more than doubles with the radiant cooling provided by the cooling plug.
