I tested out another car with UHFS. This one seemed to actually have bass. Used a tone generator app to see how low the bass went. It was mostly flat to 25Hz the fell off to nothing by 20 Hz. Small hump somewhere around 100hz (not what I'd expect for $2500). Dolby on or off didn't matter. I think some of these cars are just duds... The Tesla store people seem to be somewhat opinionless, for lack of better words.
What app did you use? I'll test mine.
I'm not surprised that the store people are opinionless. Unless they own one and really play the music it probably won't make a difference. It took several hours of playing music in my car before I really got better sound and a friend experienced the same thing when he got his. I drove up to SF last night and was playing music at 6 and the bass was almost too much at times. Dolby off did increase the intensity of the bass quite a bit. It doesn't sound like the dual 12s I had a ~decade ago, but it sounds really good.
I honestly can't imagine the stock system sounding anywhere close especially with UHFS having 3x wattage, but I'm happy to be wrong. I'd love to meet up with someone with the standard audio and put in my flash drive to see how they compare. I'd totally shut up if it doesn't make much of a difference.
