Mount your tweeters to velcro or double sided tape and move them around. Find the best location for them to image properly. You might have to mount them axially to get best results. You might want to try kickpanels (aimed at the listener), far dash or even A-pillars as well.
I'm trying to be unbiased as possable on this topic being that all of us here are PG freaks, some more than others.......You know who you are.
Idealy I would take the tweet from the Dynaudio System 242 MKII and the PG Elite mid. I've owned both, My Dynaudio set was the 240, and I have to go w/the Elites. 2 reasons. 1) being the mib and 2) being the power that the Elites will take.
The tweets on the Dyn set are so much more defined, but the Elite tweets arn't too far behind. If there was just a way to combine the 2 safely for each driver.
