Best speaker that Proac ever made


Hello,
What do you believe to be the best speaker that Proac ever made ? Stand mount and tower versions. Not limited to the reference series or any other speaker series that Proac made.

I heard the Response D40R with a Grommes phi26 a 1.75 SET amp and was blown away by the sound, the quality and the volume
My personal favorite is the response 3. That also is limited to what I have heard. I use 3's at home, and have no intention of ever selling them. I'd love to have the funds to try the 4 or 5's.
