Did you try reversing the polarity of the center speaker to see if it sounds better with the 604's?

Yes, I did check polarity of all speakers.. phasing is correct.

I ended up mounting the 604D (btw this is the early 604D with a 604C paper cone with rolled edge, I checked the numbers. There are actually two sets of Altec numbers. New numbers that are probably for the 604D and there is a number stamp with the original Altec 604C cone number. Essentially this is a 604C) in the Electro Voice Royal cabinet. For those of you not familiar with this uncommon cabinet it is a 15" speaker version of the Klipschhorn designed Aristocrat. I have never seen another Royal cabinet for sale (I've been looking). I am using three new GPA Crossovers designed just for the 604 series. They are wonderful! At this time after running through a list of good music. The 604 in the center channel is much more alive than the 15TRX. There is just something about the way the 604 projects.. the sound stage is so "in your face".. the 15TRX just didn't seem to have the same "timing" to my ear as having all 604's. And this was with changing the wires around to make sure the polarities were all correct. The bass extension in this cabinet is really good (even though it's really a corner speaker) it's close to the wall and there are no problems with the bass. It's almost like it was made for the 604. This is the Altec board maybe I'm biased, but I'm still going to say that there is something magical about Altec speakers, especially the 604 series. I'm sold!
