A recent “Paul’s Posts” about moving air got me wondering how altitude / air pressure affects speaker reproduction. I imagine greater excursion is required as altitude increases to achieve sea level loudness, but deeper thought brings on brain melt.
If there is a tangible relationship, how does FR series development compensate for those who don’t live at Boulder’s altitude?

It seems to me we should expect a proportional relationship between air density and spl.
The means to compensate for that is your volume control.
Turning it up will compensate for volume, but I’m curious about the tradeoffs, if any. Does higher excursion for a given spl result in distortion at lower volume? I also wonder if drivers having to travel further to work their magic reduces their resolution. Or maybe it doesn’t make a practical difference.
Obviously Chris Brunhaver would be the one to answer these questions.
But just intuitively, turning up the volume, which works the drivers harder, improves resolution at least in my case.
