Elevation

I was wondering. Does elevation effect your db score? will it be different if you are in denver vs in orlando or in la?

It will be different because your box tuning will change with the speed of sound at the different elevations. Your peak freq will change as well.

sounds good to me lol

that is what I thought. So pretty much we are gonna loose about 2-3 db right?

high elevations have less dense air, making your speakers less resistant to the air pressure. they become more efficient but cannot move the same amount of air compared to sea level

Whole lot more to it than that. Density is part of the issue, but not all of it. The speed of sound is independant of density and it is what is going to determine your max amplitude frequency and the tuning of the enclosure. You might lose some dBs you might gain a fraction. Almost impossible to say. What can be said is that if you did a lot of tuning at one altitude and temp., any deviation from that pressure altitude and temp will have measurable results.
