We have never taken a comparison decibel reading between the two different resonator sizes. I can break it down in a scale for you from 1-10.

(1) Being the quietest which is the 18"

(6.5) "Roughly" would be the level of the 12"

(10) Non resonated "Loudest"

So you see the 12" resonator is slightly biased towards the louder side and not quite in the middle.

I hope that this helps.

Thank you, Tony
