I’m probably going to end up buying this alarm package but you really need to do some research on sound decibel ratings. To anyone that knows anything about sound, they will laugh at a 160 db siren rating. I engineer 80,000 watt concert systems that peak at 143-145db. 150db is a jet engine at take off. AT the engine, not a 1000 feet away. When you say almost 300db……..you need to do more research. Every time you double the speakers you gain 3db of output. You don’t add the ratings together.
