That's what I was feeling as well (post above). I feel like part of the problem besides a straight up bug, or an engineer sending out a crap eq to everyone on accident is them trying to actively balance 8in and 10in subs. They should have went for a 12in in the back and had it handle 30-80hz only. Instead, it feels like the 10in handles 60-80hz with an insane rolloff on the bottom end.
BTW, any audiophile newbies who need a lesson in subs, play this song in your model 3:

Once the main song actually starts, you can clearly hear the first bass note hit and slowly morph into a lower note. This hits pretty well, but I'm not sure if it's the door or 10 in sub, would have to test when it wouldn't annoy neighbors. Immediately after, it starts a new, lower bass note and morphs that lower. This is the bass line. The sound system can't even replicate the beginning of that second note, let alone the bottom (where it sounds the sexiest).
Here is another example. There are four bass notes in the bass melody, played in descending frequency. The 4th and lowest note is about 30hz. The model 3 can't even replicate the 3rd note:
