Hi guys, I bought my Model S about two months ago and have a question about the standard speaker system. From what I've read, the standard speaker system has 7 speakers while the premium has 12 (11 tweeters and 1 subwoofer). I looked in my car, however, and can see speaker grills in what look to be nine places: One on each door, one in each corner on the dashboard, one on each side just a few inches away just up the sides, and one in the center. Shining my flashlight through the grills, I can clearly see the small tweeters on the sides in the front and on the doors. I don't have the angle to see through the far front dash area, but just go by what I think I'm hearing. Most of the threads I read about the standard vs premium systems were dated around 2013. Has the standard system changed for the latest vehicles? If not, can someone tell me exactly where these seven speakers are located in the car? Thank you!
