Not an issue in this case, since the "Xprite" isn't really a 200W speaker.Only by getting a bigger wattage siren or lower wattage speaker. They should match power.
I have an old speaker around somewhere. I’ll try that one to see if mine is defective or just a miss-matched wattage.So your saying switch to the Chinese stuff since they always have a need for loud? Is it possibly or more then likely a overrated speaker in wattage or a bad driver?
