>>Do you have any references to test data handy? I was hoping for maybe some test results that quantified the onset of air-compressibility non-linearity distortion.EV does, EV discovered this on there MTL-4 high cabinets, the 4-10's that were driving the mid-bass horn were developing to much air-compression causing non-linearity in the throat section of the horn and causeing the harmonic distortion to rise dramatically when driven near full power.
