    I've actually been very happy with the factory Dirac sound system in my 8 year old 335i. Think I'm gonna fire up REW and take some measurements just for fun. Never even thought about it but now I'm curious...

    @spwath, looking great! Have you messed with time alignment at all, or this all just EQ? The former is especially important in a car for imaging’s sake given the seating vs. speaker locations.

    Yeah, I do have time alignment all set up on my dsp. I have 2 presets, 1 with time alignment for me, and 1 without for enjoyment of everyone in the car.
    I can tell the time alignment really helps. Moves the soundstage from my left tweeter, to actually in front/to the sides.
    Makes sense though from what I have learned in my acoustics classes, you localize sound based on the first signal to reach you, so if the closest driver isn't delayed, it seems like most sound is coming from it.

    All that sound deadening helped a ton too. Before if I turn it up and turn up bass I hear everything rattle. Now I just hear the bass. Still can't see out my rearview mirror when it's really bumping, but no rattle sounds

    New speakers. Much beefier looking than the focals, which were already much beefier than stock. The tweeters not pictured are also like 5x heavier than the focal tweeters. In the middle of install, got new mounting brackets, but one for right door was at my house, so my mom is shipping it to me. For now ill be driving around with no door panels...

    Also have a helix director on the way to better control my dsp and volume, and allow for up to 20 different presets.

    Got director temporarily mounted in cardboard. This thing is pretty nice, controlling volume, subwoofer, tone controls, and can have 20 different sound setups.
