I'm probably going to end up buinyg 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 need to do more research. Every time you double the speakers you gain 3db of output. You don't add the ratings together.

I like a lot of these (and hate HOAs lol). I think I like the ones with the real bells, but I think they could really only be odrecative because I can't imagine being able to hear them well.
