0.07...i doubt you could tell a diff with even double that much of a change. same goes to tuning.. people really get too worked up over these numbers. any retard who knew zero about car audio could probably conclude these types of differences wouldn't add up to anything either. now i'm not saying a sensor nor any type of simulated response graph would agree with me 100%...but if your ears can tell the difference you shouldn't even expose them to bass...or sound for that matter, you could probably sell your auditory organs for billions of dollars and live the richest deaf man ever //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
