He says his mic of choice for thunderstorms is the Sennheiser MKH8040, in X-Y and ORTF positions.
Directional mikes, ie Fig-8s or Cardioids are inherently limited in LF response .. as are most (all?) LDCs.? I have a list of the best Fig-8s & Cardioids for LF response in my Files\Readme.
The most extended are the Calrec Soundfields & Core-Sound TetraMic cos I cheat.? The last 'true' Soundfield was the ST450.? All after that had LF worse than AKG C414 or Neumann U87
A Fig-8 with real extension below 30Hz, will show ULF proximity .. where a far off lightning display will make your meters go wild .. even when you don't hear anything with your Mk1 omni ears.? And that's even with the 30dB/8ve LF filters on the Soundfield & TetraMic
