geoffkait,
You stated that "I have always maintained the SPL meter and test tone method is superior to trial and error for any type of resonator, transducer, Brilliant Pebbles included." No problem. This is what you maintain. This is your opinion. You have the right to maintain your opinion just as others have the right to maintain theirs.
I maintain that there is a lot more to resonators/transducers than SPL metering. Metering may be helpful in some cases, to some extent. But there are many possible methodologies or combinations of methodologies that may be used to obtain good results. Metering is just one. If your meter-only system works for you then no one will say no. But what will work best for others is for them to discover, not for anyone else to decide.
