Truthfully given this is going into a semi open entertainment shelf no center is going to be ideal.The SVS Ultra center looks nice. Does your setup work with a rear port?
As you can see the cs400i fits but the tweeter is very close to the top shelf front bar. No way around it and I’ve run it this way for over a decade. It sounds find and room we helps. I’ve got to be very careful with my measurements for any new center. The speaker itself can be 9 inches tall but the tweeter needs to be around 7” at the very top of the dome for the driver to not be blocked. not ideal I know. No point going down that road.
I’ll look at some of the other recommendations. I also need to verify those towers are around 38”.
it’s kind of a 2 factor question. Is$1k at a different direct dealer better than $2k discounted ti $1k with what I can get at Bb. Yes that’s oversimplified I know. And the are any $1k options that will fit truly an upgrade over what I have.
I have ruled out klipsch just not my preference
