Waveguide + Surround Sound

There've been many discussions over the years about large CD speakers, but there hasn't been much about how to integrate them into surround sound setups.

My case is one that would likely be similar to many others,

The LR channels are 12" woofer + 12" waveguide (SEOS in this case).

I have numerous matching satellite speakers with 4" woofer, 3/4" tweeters. Tweeters have little waveguides.

I also have multiple matching drivers that can be used to make a center channel. 5 1/4" , 4" , 3" , 1" tweeter , 3/4" tweeter. All from the same line as the satellites.

In my case it would be 7 channels. L C R, two rear surrounds, and two width channels (left wide, right wide)

How do CD waveguide speakers interact in a surround sound environment?

Is a non-CD center channel going backwards? Should one make a CD center? I only have space under the TV, so something like a SEOS with 5 1/4" woofers on each side?

Most receivers have room correction these days. In my case Audyssey. This should likely match the levels since there's such a difference in sensitivity. I'm not sure if it brings down the LR, boosts the others, or both.

Thoughts?

I believe there won't be many differences between CD and "normal" speakers in multi-channel setup. 12" horn speakers may have narrower dispersion above ~800hz. It may be beneficial or not depending on where side seats are.

From my experience Audyssey isn't able to fully match frequency response of different speaker models. The surround may have a slightly different timbre.
