I have seen in-room measurements of the MG 20, 20.1 and 20.7. There use to be a drop in the lowest octave. They cannot simply move that much air. My Tympani IIIA basses are similar, the lowest resonant frequency is 33-34 Hz and from there it drops by about 18 dB/octave. The 3.6 I am using today are also driven by an active crossover and four channels of power amplification. They are not doing much below 40 Hz. Maybe I have to continue my modification of the Tympani IVa...
PS. Kettle drums = timpany? Timpany is playing at higher frequences, from about 55 Hz and upwards. What you hear in that track is the orchestral bass drum at about 35 Hz or so. Here an analysis of that track.
