[MX145]

I want to re-state I’m trying to find the best compromise in staging, imaging, and tonality working within the confines of minimal modification to the car since it’s painted and close to complete. Functionality of the car on the track is still my priority as I enjoy autocross more than car audio.

Based on my rudimentary testing and my experience with this car if I were to rebuild it with car audio as a priority I would put 8’s or 10’s in the kick cowl vent area and likely 3’s or 4’s in the kicks with tweeters in the corners of the dash near the pillars.

Also, as I understand, RTA testing doesn’t necessarily show staging and imaging although it appears to show the correlation of loss of image width with stereo tweeters in the center location as both SPL and frequency response go down the further I measure across the dash toward the pillar. These measurements are secondary to critical listening for me but I also want a measured comparison of the short and deep waveguides for my own curiosity. I don’t think the dash measurements are useful for anything else anyway; as what matters to me is the staging, imaging, and tonality at the driver and passenger seats.
