Challenge Electronics’ CS57-06D140-25-1X is a specialty sealed back speaker designed to be the loudest of the loud when size is a factor. Shrinking the technology behind sirens within emergency vehicles and back up alarms, this unit provides the loudest sound available for a 57mm speaker. The speaker is designed ready to sound with an IP68 rating and no need for external chambering. When you just need to be heard, the CS57 is the most practical mid-size audio component on the market.
