Is it just me or does Soundoff Signal sirens blow out speakers like crazy? We have about 27 cars in our fleet and they all run Soundoff 380R or eNERGY 400 sirens. We go through speakers all the time. My new car has 12K on it and just blew a brand new Fed Sig ES100 speaker. We've blown Soundoff, Fed Sig and Whelen speakers. It's gotten so bad that our admin is now telling us to not use the siren unless we absolutely need to. Some cars are on their 4th or 5th speakers. Can't figure it out. Anyone else having problems? I've used Systems 9000, Code 3 and Whelen sirens in the past and have NEVER blow a speaker.
