1.) The frequency and distribution of room modes is determined by the room’s dimensions.
2.) The degree of excitation depends on the positions of the loudspeakers/subs.
3.) The degree of audibility depends on the positions of the listener.
So yeah, the they won't go away. However, they can be rendered dramatically less impactful by following best practices (room quadrant acoustic polarity, null mode placement, etc).
Wrt the lightning, I'm sure we all have our own stories. Mine, a metallic pole, parking lot light ... hit approx. 20'-30' in front of me. The term "off the chart" is overused these days, myself included. However, all aspects of this lightning bolt hit would easily be in the category of "off the chart". I thought it hit me, physically I wasn't the same until the next day ... the adrenaline surge etc, being what it is. Phenomenal, words cannot do it justice. Seeking shelter under an awning covered entrance, the light pole was struck directly in front of us ... in hindsight, amazing, but at the time ...
I've made live to two track recordings for decades, analog reel-to-reel, cassette, thru DAT and hard disc, ... primarily the material was trains, both steam trains and diesel. By the 90's, I eventually ended up recording live acts I mixed, live acts I attended. Throughout I dabbled in sound effects with some quite good, attempting on several occasions here in the Midwest and in Florida, to capture some solid lightning recordings, never really got it right.
There are some good lightning recordings out there.
Btw; BTH, I'm not sure what happened, didn't keep up, but glad you didn't leave AVS.
