Thank you for your support. If there is anything else you want to see, please send it to me. I will ask the engineers to prepare it for you.

-3db, mostly based on the base frequency 1KHZ frequency comparison. If the 1KHZ frequency of the prototype is set at 15db, the other prototypes must not be lower than 12db.
