Does altitude change the sound of speakers??

Does altitude effect the sound of speakers? (Moved from Cleveland,Ohio 850' altitude to Prescott,AZ altitude 5,350')

yes it definitely does change. it's all related with sound velocity. if humidity, density or pressure increases sound velocity in air increases too. sound is lazy. sound waves tend to move to where sound velocity is lower.
there is no way to come to a conclusion with one variable like altitude because humidity has a greater impact on sound velocity. if humidity is the same on both places than higher altitude cause more absorption than lower altitude on high frequencies. and it's perceived as slight decrease in treble and attack. same happens if humidity decreases. 
it's all related with sound propagation and behavior of sound in fluids. air or water more or less same rules apply for sound propagation cause both are fluids. I'm a submariner. and whole submarine warfare and anti submarine warfare (ASW) is based on tactics regarding sound velocity profile (SVP).
