Lean on Bosso to do a calibration of a small sample of Galaxy 140s against his 2Hz mike from 2-30Hz to check for infrasonic variability and to build a proper calibration file.
Sonnie can then spread the 2Hz test limit rather effortlessly worldwide by distributing 140s with the calibration file available from the Shack.
We can call it the Bosso/Sonnie infrasonic calibration standard if bribery is absolutely necessary.
Anybody buying a Galaxy 140 will be assured that they can test down to 2Hz with reasonable accuracy and repeatability.
It could be a milestone in subwoofery.
