Thanks for posting up the review and your measurements. I've worked a little with the Dyn Esotar 6.5 in the doors of this car (Subaru Legacy) and did not get low frequency response like that on the RTA out of the box from the doors. These look to be really impressive.
I pre-ordered a pair a few months back for the wife's car and these should make an excellent pairing with the Scan mid/tweet I'm installing with these as a dedicated midbass. I'm even more excited to get them in hand and installed now
