So, I brought in my LX700h with it's "25 speaker Mark Levinson" sound sytem that costs $2660 extra, and dropped it off to check the stereo to see why it is so wimpy (very little base, 2nd and 3rd row sound terrible). Turns out, the big lower speakers in the 2nd row doors are what the service department called "Dummy" speakers - you can see them but they are not speakers, which explains why it sounds so bad in the back. I can only verify 16 speakers of the 25 it is supposed to have. If I was a lawyer, that would be a class-action lawsuit. I guess I could have gotten and Escalade and had a better stereo and more luxury gadgets, but I want this SUV to run for 15+years.
