Questions in my Head????????????????

[BassMechkanic]

what does the temperature do to the tuning and/or output db's of a box?
what does the humidity do to the tuning and/or output db's of a box?
what does the altitude do to the tuning and/or output db's of a box?

now mix a combo of them together?


I would think at sea level, low humidity, and cold at the mic, hot in the box would give highest db's

So experts what do you think?

Yes

Far from an expert... but increasing humidity, decreasing temperature, and lower altitude will make the cabin and box air more dense.

The more dense a fluid, the slower waves propagate through it... creating a longer wavelength at resonance.... (lower tuning freq)

The more dense your air, the more viscous it is... meaning it dissipates sound more rapidly.

If this affects SPL or tuning will depend on alot of variables in your setup, and how drastically the atmospheric conditions are changing. Not sure which ones are most important, but my guess is altitude, humidity, then temperature (order of importance).
