Little help needed please

I am fairly “au fait” with recording microphones, have been recording organs since the 1970’s. Does anyone know what mics were used on the bass series of the latest Octave release. I only ask as a very good friend has recorded the organ with a similar bass presence (16 Hz tone from the larger 32’ pedal pipes) using Sennheiser MK omni’s and recorded in DSD and mastered using Vivid Giya "Spirits as monitors. Is the bass true bass, or has it been slightly exaggerated for the purpose of demonstration
