Today I tested the Dynaudio e110 tweeters in the dash center location with my attempt at wave guides. The "wave guides" do help move the image a little away from direct center and clean up the sound a little bit.

I like the e110's matched up with the e650's in the kick panels currently crossed over at 3500Hz. The car sounds day and night better over the Focal 6.5 components I had in the kick panels. The mid bass now has impact, the mid range no longer has a huge spike around 500Hz and the staging is way higher. Even though the tweeters are in the center of the dash I still have good width. The center is just a little too centered for me. It sounds like the vocals are right on the cowl hood scoop. I want them directly in front of me so I'm going to try a deeper modified waveguide.
Keep in mind I'm trying to keep the dash and A pillars clean. I don't want my car to look like a stereo build. I want a clear view of all those cones in front of me as the point of this car is to drive it. I just want a decent stereo for those long drives.
