I've been asking a lot of questions lately, which you guys ave been very helpful with...so here's another. How does pressure affect the performance (in any metric) of a speaker? More specifically, is there a linear relationship to the atmospheric pressure and the frequency response arc of a speaker? Are certain frequencies affected more by higher pressures?
This question is spurred from comparing the Sennheiser pmx 100 and the pmx 200. The only difference appears to be that the former is open-backed, while the latter is a closed design. Then, on the tech-specs of a speaker I used in a project, the decibel rating is at a specific pressure. The actual output of the speakers is very different.
As a followup question, would drilling holes in closed-back headphones improve performance, and would any change in sound be predictable?
