I also have driven nearly every version of MS and MX with every audio configuration and battery (I was given an endless stream of loaners while my car was being built) and it seems that every system, in each car is different and requires different EQ .
I tune rooms And top audiophile systems for CES and RMAF and T.H.E. Show Newport Beach , and also can do an amazing job with car audio parametric EQ. I can tell you that it makes a huge difference when speaker manufacturers match drivers and levels on their speakers to .5db or better. Chapman Audio Systems discards a fairly high percentage of their drivers, and SCAN SPEAK of Denmark has some of the better QC and consistency amongst drivers . There are better (like Accuton which laser drills their drivers to balance the cones) but its pretty easy to hear large inconsistencies from Tesla to Tesla (But when it comes to dimensional consistency I saw this measuring machine that keeps the dimensional sizing accurate to thinner than human hair - measured by robots) so Tesla is about accuracy and consistency but the audio system is many orders of magnitude away from this.
So while I had planned to post my EQ curves, I decided it was pointless.
Come on, do show!
I'm quite curious to see if there's anything there that would indicate why the mid-range in the Model 3 so poor. The bass and the highs are tolerable, but in-between it's quite meh. Strings and voices sound quite muddled compared to say the mid-range Burmester in Mercs or even the mid-range Bang & Olufsen in Audis.
If I ever get over my endless stream of issues and manage to keep the car, I think I'm going to have to rip the interior apart and have a bunch of dynamat or such laid inside the panes to quell the rattles everywhere. If I do that, I might as well look into upgrading the speakers while I'm at it.
If any of you know of any decent option that would improve the mid-range clarity, please post your suggestions here.
Thank you!
