Re: Driver Break In In Procedure?I always took mine off. Back in the day I used a lot of JBL raw drivers in cabinets I built. In the factory cabinets from JBL that used the same driver-they drivers did not have the rubber "protectors".As far as I know they are there to protect the magnets during shipping/handling.Magnets can get very hot during operation-it takes a while to heat them up. Without the rubber "covers" there is more area exposed to the air-so more cooling can happen. The protectors act as a blanket-keeping some of the heat in.How much-I am not sure and have not done any testing-but any extra cooling can't be a bad thing.
