I'm glad to hear that the system sounds good so far. I'll be interested to hear what it sounds like with time alignment done, if you decide to go that far.
As far as my question was concerned, this is what I was looking for. I have a good set of 3 ways that dropped into the factory locations, but they have a metallic dome tweeter which is harsh to my ears coming off the glass. I'm really trying to avoid getting crazy with this and I'm wondering if something like your lens would reduce that effect.

Edit: I'm getting old. Turns out the tweeters were soft domes. What does that tell you about this car as a musical environment? I got lucky. I went back to where I had my system installed and asked for any unused tweeter pods and they gave me a pair of nice sleek looking pods intended for a Focal system. They even threw in some double sided tape. I put them outboard of the midranges to spread the soundstage a bit and, after experimenting, ended up with them aimed at the opposite door window. Excellent off-axis sound, far better than aimed directly. I'm loving my stereo again.
