Does altitude change the sound of speakers??

That was a good one. Going down in style.

Funny you say that. I've actually seen a flight attendant going down in style on a stiff one.

Oh, that was you in 2C?

I live at about 1,400 feet, and visit my hometown often, which is about sea level. Altitude tends to effect the pressure in my ear drum. I always tend to hear everything better at sea level, not just speakers. I think multiple factors play a role. Pressure inside the ear drum is a much bigger factor than air density in the room. 

Make sure you increase the timing by a couple ticks and lean out the carb. She’ll run fine.
